act-1 encodes an actin isoform that is required for proper body wall muscle and pharyngeal muscle structures and the motility of animals; actins have highly similar amino acid sequences; ACT-1 is identical to ACT-3; act-1 functions redundantly with two other actin isoforms, act-2 and act-3, to control cytoplasmic microfilament function in the early embryo.
Predicted to be a structural constituent of cytoskeleton. Involved in cortical actin cytoskeleton organization; embryo development; and mitotic cytokinesis. Located in striated muscle thin filament. Expressed in body wall musculature and gonad. Human ortholog(s) of this gene implicated in several diseases, including Baraitser-Winter syndrome 1; Baraitser-Winter syndrome 2; and autosomal dominant nonsyndromic deafness 20. Is an ortholog of human ACTB (actin beta).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
