The SKICH domains of SKIP and PIPP mediate plasma membrane localisation. The functions of the SKICH domains of NDP52 and CALCOCO1 are not known.

1: LC3C, bound selectively by a noncanonical LIR motif in NDP52, is required for antibacterial autophagy. von Muhlinen N, Akutsu M, Ravenhill BJ, Foeglein A, Bloor S, Rutherford TJ, Freund SM, Komander D, Randow F; Mol Cell. 2012;48:329-342. PMID:23022382

2: Crystallographic and modelling studies suggest that the SKICH domains from different protein families share a common Ig-like fold but harbour substantial structural variations. Yang Y, Wang G, Huang X, Du Z; J Biomol Struct Dyn. 2015;33:1385-1398. PMID:25187058
