Predicted to enable identical protein binding activity. Acts upstream of or within several processes, including animal organ development; cardiac muscle contraction; and negative regulation of transcription by RNA polymerase II. Predicted to be located in cell junction; cytosol; and intercellular bridge. Is expressed in alimentary system; sensory organ; and vibrissa. Used to study arrhythmogenic right ventricular cardiomyopathy. Orthologous to human PPP1R13L (protein phosphatase 1 regulatory subunit 13 like). [provided by Alliance of Genome Resources, Apr 2022]
