Summary: Predicted to enable several functions, including ATPase activator activity; ATPase binding activity; and lamin binding activity. Acts upstream of or within nuclear membrane organization and protein localization to nuclear envelope. Located in nuclear envelope. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system; and integumental system. Human ortholog(s) of this gene implicated in autosomal recessive limb-girdle muscular dystrophy type 2Y. Orthologous to human TOR1AIP1 (torsin 1A interacting protein 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
