Western blot analysis of CRK (arrow) using CRK polyclonal antibody (Cat # PAB3512). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the CRK gene (Lane 2).
Formalin-fixed and paraffin-embedded human breast carcinoma tissue reacted with CRK polyclonal antibody (Cat # PAB3512) , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry ; clinical relevance has not been evaluated.
This gene encodes a member of an adapter protein family that binds to several tyrosine-phosphorylated proteins. The product of this gene has several SH2 and SH3 domains (src-homology domains) and is involved in several signaling pathways, recruiting cytoplasmic proteins in the vicinity of tyrosine kinase through SH2-phosphotyrosine interaction. The N-terminal SH2 domain of this protein functions as a positive regulator of transformation whereas the C-terminal SH3 domain functions as a negative regulator of transformation. Two alternative transcripts encoding different isoforms with distinct biological activity have been described. [provided by RefSeq
