Interactioni

Subunit structurei

Binds the CaM kinase domain of CASK. Forms a ternary complex with CASK and LIN7A, LIN7B or LIN7C. Competes with APBA1 that forms a similar complex with CASK and LIN7 proteins. The tripartite complex CASKIN1/CASK/LIN7(A/B/C) binds the cytoplasmic tail of NRXN1 (By similarity). Polymerizes, via the tandem SAM domains, to form long, 8 nM wide fibers, upon which other proteins can assemble.By similarity1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
