    • Introduction

      TYRO3 Protein Tyrosine Kinase or TYRO3 is a transmembrane receptor tyrosine kinase. TYRO3 has crucial role in essential processes such as cell migration, actin reorganization and cell survival. It is activated and signaled by MAPK/ERK and PI3K/AKT that expedites the cellular functions of protein.

    More Info

    • Introduction

      TDP1 belongs to the phospholipase D family and contains two PLD phosphodiesterase domains. TDP1 is involved in repairing stalled topoisomerase I-DNA complexes by catalyzing the hydrolysis of the phosphodiester bond between the tyrosine residue of topoisomerase I and the 3-prime phosphate of DNA. TDP1 may also remove glycolate from single-stranded DNA containing 3-prime phosphoglycolate, suggesting a role in repair of free-radical mediated DNA double-strand breaks. Mutations in the TDP1 gene are linked to the disease spinocerebellar ataxia with axonal neuropathy (SCAN1).

    • Introduction

      Tyrosine Kinase ErbB-4 (ErbB4) is a receptor tyrosine kinase that is a member of the epidermal growth factor receptor family whose members play a role as receptors for the EGF family of growth factors. ErbB4is a single-pass type I transmembrane protein with multiple furin-like cysteine rich domains,PDZ domain binding motif, a tyrosine kinase domain and a phosphotidylinositol-3 kinase binding site. ErbB4binds its ligands with low affinity and is expressed in normal skeletal muscle, heart, pituitary, brain and some breast carcinomas. Monomeric ErbB4 takes part in neuronal development and development of the heart and cancer.

    More Info

    • Introduction

      ErbB3, also called Her3 (human epidermal growth factor receptor 3), is a type I membrane glycoprotein that is a member of the ErbB family of tyrosine kinase receptors. ErbB family members serve as receptors for the epidermal growth factor (EGF) family of growth factors. Among ErbB family members, ErbB3 is unique in that it contains a defective kinase domain. ErbB3 is expressed in keratinocytes, melanocytes, skeletal muscle cells, embryonic myoblasts and Schwann cells. Monomeric ErbB3 serves as a low affinity receptor for the heregulins (HRG). ErbB3 can induce specific antibody production in vivo, hence to inhibit tumor cell growth. ErbB-3 can be used to treat early, medium and advanced or post-operative breast cancer with over-expression of ErbB2. According to its mechanism of action, ErbB3 is classified as a therapeutic for cancer.

    More Info

    • Introduction

      HER-2/neu (erbB-2) encodes an 185-kDa orphan receptor tyrosine kinase that is constitutively active as a dimer and displays potent oncogenic activity when overexpressed. Herstatin, as the product of alternative HER-2 transcript, retains intron 8.
      The herstatin mRNA is expressed in normal human fetal kidney and liver, but is at reduced levels relative to p185HER-2 mRNA in carcinoma cells that contain an amplified HER-2 gene. Herstatin appears to be an inhibitor of p185HER-2, because it disrupts dimers, reduces tyrosine phosphorylation of p185, and inhibits the anchorage-independent growth of transformed cells that overexpress HER-2.

    • Background

      HER2 / ErbB2 (human epidermal growth factor receptor 2) is a member of the ErbB family of receptor tyrosine kinases. It plays a role in cell signalling related to growth, differentiation and proliferation.

      erbB-2 encodes a 185-kDa orphan receptor tyrosine kinase that is constitutively active as a dimer and displays potent oncogenic activity when overexpressed.

      ErbB2 works as a receptor that, upon ligand binding activates downstream signalling pathways such as the MAPK and PI3K/AKT pathways, promoting cell proliferation and survival.

      The activation of ErbB2 leads to enhanced cell growth and survival, making it critical in normal cellular functions and in the pathogenesis of cancer.

      Herstatin, as the product of alternative HER-2 transcript, retains intron 8.
      The herstatin mRNA is expressed in normal human fetal kidney and liver, but is at reduced levels relative to p185HER-2 mRNA in carcinoma cells that contain an amplified HER-2 gene. Herstatin appears to be an inhibitor of p185HER-2, because it disrupts dimers, reduces tyrosine phosphorylation of p185, and inhibits the anchorage-independent growth of transformed cells that overexpress HER-2.

About Tyrosine kinase:

Tyrosine kinase is a type of enzyme that can transfer phosphate groups from ATP to protein in the cell. Tyrosine kinases are, therefore, a type of protein kinase.

Tyrosine kinase Function
Kinases, like transferases, are responsible for catalyzing the transfer of phosphoryl groups from a nucleoside triphosphate donor to an acceptor molecule. Thus, they are involved in ATP metabolism and a crucial part of cellular respiration.
While tyrosine kinases are a subclass of protein kinases, they also have a variety of functions throughout the cell and are critical for reacting to events in the body.
Tyrosine kinase activity, for instance, regulates cell cycle control and the properties of transcription factors. It assists in the process of mitogenesis and the induction of mitosis.
The degree to which cells grow and develop may also respond to tyrosine kinase activity. Kinases are involved in energy sensing, telling the cell whether it should use energy to reproduce or conserve its resources until more food comes along. Tyrosine kinases have been observed to help stabilize DNA, suggesting that they have a reparative role in the cell, especially when the conditions for reproduction are not met.

Tyrosine kinase Interactions
Tyrosine kinases may have substantial clinical significance. Evidence suggests that excessive levels of tyrosine kinase may not be beneficial for the body. Genetic mutations in which the levels of tyrosine kinase are perpetually elevated are associated with the formation of several specific cancers. Many drug development companies are now looking at molecules that can inhibit the action of tyrosine kinases in the body in an attempt to prevent the disease from taking hold.
Clinical trials investigating the effect of tyrosine kinase inhibitors are ongoing. One study using the drug Gefitinib appears to have had favorable results in patients with non-small cell lung cancer.
Certain types of cancers do not respond well to standard chemotherapy treatments, particularly gastrointestinal stromal tumors. Researchers have found that certain types of tyrosine inhibitors, such as imatinib, are useful in these cases. These tumors are characterized by being bundles of crosslinked smaller tumors. The belief is that tyrosine inhibitors prevent the excessive division of these kinds of cells, reducing their growth rate.
Enhanced activity of tyrosine kinase is also related to a host of other health problems. For instance, cells with elevated tyrosine kinase tend to experience difficulties in cell division. Higher than normal levels are also associated with chronic conditions, such as psoriasis and atherosclerosis.

Tyrosine kinase Structure
Tyrosine kinase contains many of the structures common to practically all protein kinases, even if the specific structure of the molecule is somewhat different from other types of protein kinase.
Tyrosine kinases have an ATP binding site and two peptide sequences. They also sometimes have a catalytic site made of amino acid. More than 100 structures of tyrosine kinases are now held in the Protein Data Bank.
Other factors regulate most tyrosine kinase enzymes. Many, for instance, are bound reversibly by a protein. Recycled tyrosine kinases eventually find their way back to the lysosome, where they become an essential component of the digestion process.
