Predicted to enable chromatin DNA binding activity. Involved in heart formation; negative regulation of protein kinase B signaling; and neurogenesis. Acts upstream of or within negative regulation of MAPK cascade and skeletal muscle cell differentiation. Located in nuclear membrane. Is expressed in several structures, including heart; liver; nephric duct; neural tube; and tibialis anterior. Human ortholog(s) of this gene implicated in cataract 46 juvenile-onset. Orthologous to human LEMD2 (LEM domain nuclear envelope protein 2). [provided by Alliance of Genome Resources, Apr 2022]
