Function

[CRK_HUMAN] The Crk-I and Crk-II forms differ in their biological activities. Crk-II has less transforming activity than Crk-I. Crk-II mediates attachment-induced MAPK8 activation, membrane ruffling and cell motility in a Rac-dependent manner. Involved in phagocytosis of apoptotic cells and cell motility via its interaction with DOCK1 and DOCK4. May regulate the EFNA5-EPHA3 signaling.^[1] ^[2] ^[3]

Publication Abstract from PubMed

CRKI (SH2-SH3) and CRKII (SH2-SH3-SH3) are splicing isoforms of the oncoprotein CRK that regulate transcription and cytoskeletal reorganization for cell growth and motility by linking tyrosine kinases to small G proteins. CRKI shows substantial transforming activity, whereas the activity of CRKII is low, and phosphorylated CRKII has no biological activity whatsoever. The molecular mechanisms underlying the distinct biological activities of the CRK proteins remain elusive. We determined the solution structures of CRKI, CRKII and phosphorylated CRKII by NMR and identified the molecular mechanism that gives rise to their activities. Results from mutational analysis using rodent 3Y1 fibroblasts were consistent with those from the structural studies. Together, these data suggest that the linker region modulates the binding of CRKII to its targets, thus regulating cell growth and motility.
