|WB||Use a concentration of 1 mg/ml. Detects a band of approximately 36 kDa (predicted molecular weight: 34 kDa).|
FunctionThe 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.
Sequence similaritiesBelongs to the CRK family.
Contains 1 SH2 domain.
Contains 2 SH3 domains.
DomainThe C-terminal SH3 domain function as a negative modulator for transformation and the N-terminal SH3 domain appears to function as a positive regulator for transformation.
The SH2 domain mediates interaction with SHB.
modificationsPhosphorylation of Crk-II (40 kDa) gives rise to a 42 kDa form.
Phosphorylated on Tyr-221 upon cell adhesion. Results in the negative regulation of the association with SH2- and SH3-binding partners, possibly by the formation of an intramolecular interaction of phosphorylated Tyr-221 with the SH2 domain. This leads finally to the down-regulation of the Crk signaling pathway.
Cellular localizationCytoplasm. Cell membrane. Translocated to the plasma membrane upon cell adhesion.
