Biogenesis of lysosome-related organelles complex 1 subunit 1

Gene

BLOC1S1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Component of the BLOC-1 complex, a complex that is required for normal biogenesis of lysosome-related organelles (LRO), such as platelet dense granules and melanosomes. In concert with the AP-3 complex, the BLOC-1 complex is required to target membrane protein cargos into vesicles assembled at cell bodies for delivery into neurites and nerve terminals. The BLOC-1 complex, in association with SNARE proteins, is also proposed to be involved in neurite extension. May negatively regulate aerobic respiration through mitochondrial protein lysine-acetylation. May counteract the action of the deacetylase SIRT3 by acetylating and regulating proteins of the mitochondrial respiratory chain including ATP5A1 and NDUFA9.2 Publications

Isoform 2 (identifier: P78537-2) [UniParc]FASTAAdd to basket

The sequence of this isoform differs from the canonical sequence as follows:
     1-28: Missing.

Note: May be produced by alternative initiation at Met-27 of isoform 1. A polymorphism at position 9 leads to the creation of a stop codon. Isoform 2 is the the only form that exists in orthologs (except primates).
