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.1 Publication
