产品介绍 ABT1 (activator of basal transcription 1) is a nuclear protein that associates with the TATA-binding protein (TBP) and enhances basal transcription activity of class II promoters. ABT1 associates with TBP in HeLa nuclear extracts in vitro. Another protein, designated ERF, is a member of the Ets family of transcription factors. The members of the Ets family are grouped because they share a highly conserved DNA binding domain. These factors are involved in growth factor pathways and regulate both proliferation and differentiation. ERF (Ets-2 repressor factor) is a ubiquitously expressed Ets-domain protein that exhibits strong transcriptional repressor activity, suppresses Ets-induced transformation and is regulated by MAPK phosphorylation. ERF transcription may be regulated by Ets-domain proteins. Additionally, modulation of ERF activity is involved in the transcriptional regulation of genes activated during entry into G1 phase.

Function : Potent transcriptional repressor that binds to the H1 element of the Ets2 promoter. May regulate other genes involved in cellular proliferation. Required for extraembryonic ectoderm differentiation, ectoplacental cone cavity closure, and chorioallantoic attachment (By similarity). May be important for regulating trophoblast stem cell differentiation.

Subcellular Location : Nucleus.

Tissue Specificity : Highest levels in testis, ovary, pancreas, and heart.

Post-translational modifications : Phosphorylated by multiple kinases including MAPK1/ERK2 at THR-526.

Phosphorylation regulates the activity of ERF.

Similarity : Belongs to the ETS family.

Contains 1 ETS DNA-binding domain.

细胞膜受体（Membrane Receptors) c-erbB-4蛋白过去一直为乳腺癌基因研究的主要方向，研究乳腺癌组织学分级及术后生存期的关系。目前认为他与细胞增殖活性和激素受体有一定的关联，有学者将c-erbB-4蛋白研究用于神经内分泌蛋白为主。
