Descriptions

MEF2 factors regulate transcription during cardiac and skeletal myogenesis. Phosphorylation by p38 at Thr 293 and Thr 300 within a linker region, and Ser 387 within transcription repressor domain enhances MEF2C activity allosterically, which implicates potential mechanism of autoinhibition.

1 GO annotations of cellular component

Name Definition
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

4 GO annotations of molecular function

Name Definition
chromatin binding Binding to chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
DNA-binding transcription factor activity, RNA polymerase II-specific A DNA-binding transcription factor activity that modulates the transcription of specific gene sets transcribed by RNA polymerase II.
protein dimerization activity The formation of a protein dimer, a macromolecular structure consists of two noncovalently associated identical or nonidentical subunits.
RNA polymerase II cis-regulatory region sequence-specific DNA binding Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by RNA polymerase II.

5 GO annotations of biological process

Name Definition
apoptotic process A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
cell differentiation The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
nervous system development The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.
positive regulation of transcription by RNA polymerase II Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
regulation of transcription by RNA polymerase II Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.
