About MYO1B

Cytogenetic location: 2q32.3 Genomic coordinates (GRCh38): 2:191,245,404-191,425,386 (from NCBI)

This gene has 15 transcripts (splice variants), 211 orthologues and 43 paralogues. Broad expression in liver (RPKM 53.1), lung (RPKM 45.2) and 23 other tissues.

Summary

Enables ATP binding activity; actin filament binding activity; and microfilament motor activity. Involved in actin filament organization and post-Golgi vesicle-mediated transport. Located in several cellular components, including actin filament; endosome; and perinuclear region of cytoplasm. Colocalizes with trans-Golgi network membrane.
