Summary: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity; chromatin binding activity; and lncRNA binding activity. Involved in negative regulation of DNA-templated transcription; synaptic vesicle cycle; and white fat cell differentiation. Acts upstream of or within Notch signaling pathway and negative regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription repressor complex. Is active in GABA-ergic synapse; glutamatergic synapse; and presynaptic active zone cytoplasmic component. Is expressed in several structures, including central nervous system; chorionic plate; genitourinary system; limb; and lung. Orthologous to human CTBP1 (C-terminal binding protein 1).

MCRIP1 interferes with interactions of CtBP with the lung-enriched transcriptional repressors, Foxp1 and Foxp2, thereby preventing the recruitment of the CtBP co-repressor complex to the SP-B and SP-C promoters and maintaining them in an active chromatin state. Homozygous deficiency of Mcrip1 in mice causes fatal respiratory distress due to abnormal transcriptional repression of surfactant 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.
