Primary antibody说明Steroid and thyroid hormones and retinoic acid regulate a complex array of gene expression activity via intracellular receptor transcription factors belonging to the ligand-dependent nuclear receptor superfamily. Adding to the complexity of function of these transcription factors are associated proteins known as coactivators and corepressors which, as their names suggest, enhance or depress transcription activity of the nuclear receptor with which they associate. Glucocorticoid receptor interacting protein-1 (GRIP 1), or Transcription Intermediary Factor 2 (TIF 2), is a member of a family of transcriptional coactivator proteins which includes steroid receptor coactivator-1 (SRC 1) and Amplified in breast cancer-1 (AIB 1).
GRIP1 has been shown to interact and stimulate transcriptional activity of the retinoic acid, retinoid X, vitamin D, mineralocorticoid, glucocorticoid, thyroid hormone, androgen, estrogen, progesterone, and peroxisome proliferator activated receptors. GRIP 1 also contains several copies of the conserved LXXLL/LLXXL motif which has been demonstrated to be critical to receptor-coactivator interactions.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
应用说明Is unsuitable for WB.
功能Transcriptional coactivator for steroid receptors and nuclear receptors. Coactivator of the steroid binding domain (AF-2) but not of the modulating N-terminal domain (AF-1). Required with NCOA1 to control energy balance between white and brown adipose tissues.
疾病相关Note=Chromosomal aberrations involving NCOA2 may be a cause of acute myeloid leukemias. Inversion inv(8)(p11;q13) generates the KAT6A-NCOA2 oncogene, which consists of the N-terminal part of KAT6A and the C-terminal part of NCOA2/TIF2. KAT6A-NCOA2 binds to CREBBP and disrupts its function in transcription activation.
序列相似性Belongs to the SRC/p160 nuclear receptor coactivator family. Contains 1 bHLH (basic helix-loop-helix) domain. Contains 1 PAS (PER-ARNT-SIM) domain.
结构域Contains four Leu-Xaa-Xaa-Leu-Leu (LXXLL) motifs. The LXXLL motifs are essential for the association with nuclear receptors and are, at least in part, functionally redundant. The LLXXLXXXL motif is involved in transcriptional coactivation and CREBBP/CBP binding. Contains 2 C-terminal transcription activation domains (AD1 and AD2) that can function independently.
翻译后修饰Phosphorylated upon DNA damage, probably by ATM or ATR.
