Summary: Enables alpha-catenin binding activity and transcription corepressor activity. Involved in several processes, including miRNA-mediated gene silencing by inhibition of translation; negative regulation of hippo signaling; and regulation of cellular response to hypoxia. Acts upstream of or within miRNA-mediated post-transcriptional gene silencing and positive regulation of protein-containing complex assembly. Located in several cellular components, including Golgi apparatus; P-body; and nucleoplasm. [provided by Alliance of Genome Resources, Dec 2024]

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.
