Is predicted to encode a protein with the following domains: PHR; Zinc finger, RING/FYVE/PHD-type; PHR domain; Zinc finger, RING-type; Galactose-binding-like domain superfamily; Ring finger domain; Regulator of chromosome condensation, RCC1; Regulator of chromosome condensation 1/beta-lactamase-inhibitor protein II; APC10/DOC domain; PHR domain superfamily; and Regulator of chromosome condensation (RCC1) repeat. Is an ortholog of C. elegans F07B7.12 and rpm-1. In C. elegans, rpm-1 is involved in several processes, including dorsal/ventral axon guidance; negative regulation of intracellular signal transduction; and regulation of cellular component organization.
