ARPIN is down-regulated in breast cancer cells and predicts poor prognosis in breast cancer patients. Data suggest that restoration of ARPIN in breast cancer cells suppresses cell proliferation, colony formation, cell cycle distribution, invasion in vitro, and tumorigenesis in vivo (xenograft experiments in nude mice); Arpin acts as tumor suppressor in breast cancer and is associated with inhibition of Akt signaling.

Title: Clinicopathological and prognostic significance of aberrant Arpin expression in gastric cancer.
Data reveal that Arpin is comprised of an elongated globular core from which the C-terminal tail extends as a linear peptide, thus forming a primary epitope that is readily available to tether Arpin to interacting proteins.

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.
