SifA And Kinesin-Interacting Protein
This gene encodes a protein that binds the plus-end directed microtubule motor protein kinesin, together with the lysosomal GTPase Arl8, and is required for lysosomes to distribute away from the microtubule-organizing center. The encoded protein belongs to the multisubunit BLOC-one-related complex that regulates lysosome positioning. It binds a Salmonella effector protein called Salmonella induced filament A and is a critical host determinant in Salmonella pathogenesis. It has a domain architecture consisting of an N-terminal RPIP8, UNC-14, and NESCA (RUN) domain that binds kinesin-1 as well as the lysosomal GTPase Arl8, and a C-terminal pleckstrin homology domain that binds the Salmonella induced filament A effector protein. Naturally occurring mutations in this gene lead to abnormal localization of lysosomes, impaired autophagy flux and are associated with recessive dilated cardiomyopathy and left ventricular noncompaction.

Forensic Context
A study in mice demonstrated that the PLEKHM2 is a validated mis-spliced target in the hearts of a cardiomyocyte-specific Mbnl1/Mbnl2 double knockout model, with splicing alterations strictly concordant between RNA-seq and RT-PCR validation [Lee et al. DOI:10.1093/hmg/ddac108].
