Summary: Involved in several processes, including chromosome attachment to the nuclear envelope; protein localization to euchromatin; and regulation of gene expression. Located in autosome and euchromatin. Is expressed in several structures, including AB; C; germ cell; germ line; and somatic cell. Orthologous to several human genes including MORF4L2 (mortality factor 4 like 2). [provided by Alliance of Genome Resources, Dec 2024]
