|PROSITE documentation PDOC51290 [for PROSITE entry PS51290]|
The multidomain protein Connector enhancer of kinase suppressor of ras (Connector enhancer of KSR) (CNK) functions as a scaffold in several signal cascades and acts on proliferation, differenciation and apoptosis. CNK connects upstream activators and downstream targets of Ras- and Rho-dependent signaling pathways and may allow cross-talks between these pathways. In invertebrates, CNK is expressed as one isoform, whereas in mammals there exists CNK1, CNK2A, and its splice variant CNK2B. CNK proteins consist of one sterile α motif (SAM) domain (see <PDOC50105>), one conserved region in CNK (CRIC) domain, one PSD-96/Dlg-A/ZO-1 (PDZ) domain (see <PDOC50106>), and one pleckstrin homology (PH) domain (see <PDOC50003>). The CRIC domain is enriched in leucine residues and functions as a protein-protein interaction domain [1,2].
The profile we developed covers the entire CRIC domain.Last update:
