| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Enables several functions, including RNA polymerase II-specific DNA-binding transcription factor binding activity; chromatin binding activity; and transcription corepressor activity. Involved in several processes, including cerebral cortex neuron differentiation; negative regulation of circadian rhythm; and regulation of axon extension. Acts upstream of or within several processes, including cellular response to glucose stimulus; negative regulation of transcription by RNA polymerase II; and positive regulation of G2/M transition of mitotic cell cycle. Located in kinetochore and nucleus. Part of transcription repressor complex. Is expressed in several structures, including blastocyst-stage conceptus; central nervous system; early embryo; genitourinary system; and paraxial mesenchyme. Human ortholog(s) of this gene implicated in chromosome 15q24 deletion syndrome. Orthologous to human SIN3A (SIN3 transcription regulator family member A). PHENOTYPE: Targeted disruption of this gene results in early embryonic lethality. Homozygous null MEFs display poor cell proliferation, reduced S-phase and increased G2/M fractions, a block in DNA replication, and enhanced apoptosis; however, no increase in chromosomal instability is observed.
