Myo1b Gene Summary [Mouse]
Predicted to enable several functions, including actin filament binding activity; anion binding activity; and calmodulin binding activity. Acts upstream of or within transferrin transport. Located in brush border. Is expressed in 1st branchial arch mandibular component; central nervous system; facial prominence; head surface ectoderm; and sensory organ. Orthologous to human MYO1B (myosin IB). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Myo1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
