Summary: Predicted to enable transmembrane transporter binding activity. Predicted to be involved in several processes, including negative regulation of mitotic cell cycle phase transition; regulation of membrane depolarization; and regulation of potassium ion transport. Predicted to be located in cytosol; nucleus; and plasma membrane.

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.
