Inactive Tyrosine-Protein Kinase 7 (PTK7) Antibody
Por favor contáctenos para obtener información detallada sobre el precio y disponibilidad.
Description
Receptor protein tyrosine kinases transduce extracellular signals across the cell membrane. A subgroup of these kinases lack detectable catalytic tyrosine kinase activity but retain roles in signal transduction. The protein encoded by this gene is a member of this subgroup of tyrosine kinases and may function as a cell adhesion molecule. This gene is thought to be expressed in colon carcinomas but not in normal colon, and therefore may be a marker for or may be involved in tumor progression. Four transcript variants encoding four different isoforms have been found for this gene.Tissue specificity: Highly expressed in lung, liver, pancreas, kidney, placenta and melanocytes. Weakly expressed in thyroid gland, ovary, brain, heart and skeletal muscle. Also expressed in erythroleukemia cells. But not expressed in colon.

Descripción
Protein Tyrosine Kinase 7 (PTK7) is an inactive receptor tyrosine kinase that plays a critical role in cell signaling, development, and Wnt pathway regulation. Unlike other kinases, PTK7 lacks catalytic activity due to mutations in its kinase domain but functions as a co-receptor to regulate signaling pathways. Structurally, PTK7 has multiple extracellular immunoglobulin-like domains, a transmembrane region, and a pseudokinase domain. It is widely expressed during embryonic development and in adult tissues, particularly in processes involving cell polarity, migration, and morphogenesis. PTK7 is crucial for Wnt signaling, especially the non-canonical planar cell polarity (PCP) pathway, where it regulates tissue organization and cell orientation. It also modulates processes such as angiogenesis, neural development, and epithelial cell migration. PTK7 has been implicated in cancer progression, including colorectal cancer, gastric cancer, and leukemia, where it promotes metastasis, angiogenesis, and resistance to apoptosis. Altered PTK7 expression is associated with poor prognosis in cancer patients. Given its importance in development and disease, PTK7 is being explored as a therapeutic target in oncology and regenerative medicine.
