Predicted to enable GTPase regulator activity and transcription coactivator activity. Predicted to be involved in maintenance of protein location in nucleus and positive regulation of tyrosine phosphorylation of STAT protein. Predicted to be located in centrosome; cytoplasm; and midbody. Predicted to be active in mitochondrial intermembrane space. Is expressed in urinary system. Used to study male infertility and retinitis pigmentosa with or without situs inversus. Human ortholog(s) of this gene implicated in retinitis pigmentosa with or without situs inversus. Orthologous to human ARL2BP (ADP ribosylation factor like GTPase 2 binding protein). [provided by Alliance of Genome Resources, Apr 2022]
