MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] BLOC1S1 is a component of the ubiquitously expressed BLOC1 multisubunit protein complex. BLOC1 is required for normal biogenesis of specialized organelles of the endosomal-lysosomal system, such as melanosomes and platelet dense granules (Starcevic and Dell'Angelica, 2004 [PubMed 15102850]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Homozygous inactivation of this gene leads to embryonic lethality. Mouse embryonic fibroblasts show alterations in autophagy, mitochondrial physiology, and vesicle-mediated transport. [provided by MGI curators]
