PLEKHM2 - pleckstrin homology and RUN domain containing M2 Gene
Also Known as SKIP
Species: Homo sapiens
About PLEKHM2
This gene has 5 transcripts (splice variants), 207 orthologues, 13 paralogues and is associated with 1 phenotype. Ubiquitous expression in bone marrow (RPKM 21.8), testis (RPKM 21.5) and 25 other tissues.
Summary
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.
