Summary: Enables phosphatidylinositol-3,4,5-trisphosphate binding activity; phosphatidylinositol-3,4-bisphosphate binding activity; and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in Fc-gamma receptor signaling pathway involved in phagocytosis and T cell mediated immunity. Acts upstream of or within several processes, including T cell meandering migration; cell gliding; and phagocytosis. Located in several cellular components, including lamellipodium; microvillus; and phagocytic cup. Orthologous to human MYO1G (myosin IG). [provided by Alliance of Genome Resources, Dec 2024]

Myo1g is required for efficient adhesion and migration of activated B lymphocytes to inguinal lymph nodes.
Title: Myo1g is required for efficient adhesion and migration of activated B lymphocytes to inguinal lymph nodes.
The results described here reveal a novel molecular mechanism by which Myo1g mediates and regulates cell stiffness in B-lymphocytes.
Title: Myo1g is an active player in maintaining cell stiffness in B-lymphocytes.
Study found that the unconventional myosin 1g (Myo1g) motor generates membrane tension, enforces cell-intrinsic meandering search, and enhances T-DC interactions during lymph-node surveillance. Increased turning and meandering motility, as opposed to ballistic motility, is enhanced by Myo1g. Myo1g acts as a "turning motor" and generates a form of cellular "flanerie."
Title: Detection of rare antigen-presenting cells through T cell-intrinsic meandering motility, mediated by Myo1g.
Myosin 1g regulates cytoskeleton plasticity, cell migration, exocytosis, and endocytosis in B lymphocytes.
Title: Myosin 1g regulates cytoskeleton plasticity, cell migration, exocytosis, and endocytosis in B lymphocytes.
Data propose that Myo1G regulates cell elasticity by deformations of the actin network at the cell cortex.
Title: Myosin 1G (Myo1G) is a haematopoietic specific myosin that localises to the plasma membrane and regulates cell elasticity.

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.
