Summary: Enables cysteine-type endopeptidase inhibitor activity. Acts upstream of or within homologous chromosome segregation and mitotic sister chromatid cohesion. Located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; eye; limb; mesonephric tubule of male; and testis. Orthologous to several human genes including PTTG1 (PTTG1 regulator of sister chromatid separation, securin). [provided by Alliance of Genome Resources, Apr 2022]

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.
