Summary: Predicted to enable gamma-tubulin binding activity and protein C-terminus binding activity. Involved in several processes, including animal organ development; anterograde synaptic vesicle transport; and lysosomal protein catabolic process. Located in cytosol and lysosome. Part of BLOC-1 complex. Is expressed in several structures, including brain; eye; genitourinary system; gut; and spinal cord. Orthologous to human BLOC1S2 (biogenesis of lysosomal organelles complex 1 subunit 2). [provided by Alliance of Genome Resources, Apr 2022]

BLOS2 physically interacted with Notch1 in endo-lysosomal trafficking of Notch1. The findings suggest that BLOS2 is a novel negative player in regulating Notch signaling through lysosomal trafficking to control multiple stem and progenitor cell homeostasis in vertebrates.

These findings reveal that balanced control of Notch signaling by BLOS2 is required for HSC homeostasis during fetal liver hematopoiesis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
