PA5-29839 targets CCK4 in IHC (P) and WB applications and shows reactivity with Human samples.
The PA5-29839 immunogen is recombinant protein fragment corresponding to a region within amino acids 11 and 209 of Human CCK4.
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.
