Is predicted to encode a protein with the following domains: Anaphase-promoting complex subunit 4 WD40 domain; WD domain, G-beta repeat; WD40-repeat-containing domain superfamily; WD40 repeat; WD repeat-containing protein 47; WD40/YVTN repeat-like-containing domain superfamily; and Anaphase-promoting complex subunit 4, WD40 domain. Is an ortholog of C. elegans nmtn-1.
