      Alternate Names
      • CTG repeat protein 26
      • Silencing mediator of retinoic acid and thyroid hormone receptor
      • T3 receptor-associating factor
      • Thyroid-, retinoic-acid-receptor-associated corepressor
      • nuclear receptor co-repressor 2
      • silencing mediator for retinoid and thyroid hormone receptors
      Background InformationThe Silencing mediator of retinoic acid & thyroid hormone receptor protein, commonly called the SMRT protein mediates the transcriptional repression of some nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription machinery. Consistent with this activity, this protein is known to form a large corepressor complex containing SIN3A/B and histone deacetylases HDAC1 and HDAC2. SMRT is also a component of the N-Cor repressor (nuclear receptor corepressor), a multi-subunit complex minimally composed of NCOR1, NCOR2, HDAC3, TBL1X, TBL1R, CORO2A and GPS2. SMRT and nuclear receptor corepressor N-CoR are related transcriptional corepressors which contain two distinct domains capable of interacting with unliganded nuclear receptors to repress their basal transcriptional activity.

      SIZE: 2517 amino acids; 274034 Da

      SUBUNIT: Interacts with HDAC7 (By similarity). Forms a large corepressor complex that contains SIN3A/B and histone deacetylases HDAC1 and HDAC2. This complex associates with the thyroid (TR) and the retinoid acid receptors (RAR) in the absence of ligand, and may stabilize their interaction with TFIIB. The SRMT isoform interacts with HDAC10. Interacts with MINT. Component of the N-Cor repressor complex, at least composed of NCOR1, NCOR2, HDAC3, TBL1X, TBL1R, CORO2A and GPS2. Interacts with CBFA2T3.


      TISSUE SPECIFICITY: Ubiquitous. High levels of expression are detected in lung, spleen and brain.

      DOMAIN: SwissProt: Q9Y618 The N-terminal region contains repression functions that are divided into three independent repression domains (RD1, RD2 and RD3). The C-terminal region contains the nuclear receptor- interacting domains that are divided in two separate interaction domains (ID1 and ID2). & The two interaction domains (ID) contain a conserved sequence referred to as the CORNR box. This motif is required and sufficient to permit binding to unligated TR and RARS. Sequences flanking the CORNR box determine nuclear hormone receptor specificity.

      SIMILARITY: Belongs to the N-CoR nuclear receptor corepressors family. & Contains 2 SANT domains.
