Descriptions

Human progesterone receptor A (PR-A) and B (PR-B) isoforms are members of the nuclear receptor family of ligand-activated transcription factors. The two PR proteins are identical except that PR-B contains an additional 164 N-terminal amino acids in the B upstream segment (BUS). <br>In PR-B, the deletion of the autoinhibitory region increases the transcriptional activity. In PR-A, deletion of the same region also increases its transcriptional activity. The autoinhibitory region contains a SUMO-1 binding motif (IKEE) and mutation within the motif leads to loss of autoinhibitory function.

2 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.

5 GO annotations of molecular function

Name Definition
estrogen response element binding Binding to an estrogen response element (ERE), a conserved sequence found in the promoters of genes whose expression is regulated in response to estrogen.
nuclear receptor activity A DNA-binding transcription factor activity regulated by binding to a ligand that modulates the transcription of specific gene sets transcribed by RNA polymerase II. Nuclear receptor ligands are usually lipid-based (such as a steroid hormone) and the binding of the ligand to its receptor often occurs in the cytoplasm, which leads to its tranlocation to the nucleus.
nuclear steroid receptor activity Combining with a steroid hormone and transmitting the signal within the cell to initiate a change in cell activity or function.
steroid binding Binding to a steroid, any of a large group of substances that have in common a ring system based on 1,2-cyclopentanoperhydrophenanthrene.
zinc ion binding Binding to a zinc ion (Zn).

2 GO annotations of biological process

Name Definition
intracellular steroid hormone receptor signaling pathway The series of molecular signals initiated by a steroid binding to an intracellular steroid hormone receptor.
regulation of transcription by RNA polymerase II Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.
