a transcription factor that is a member of the leucine zipper family. Isolated and characterized as the cAMP-response element binding protein 2 (CREB-2). Involved in cisplatin resistance. Other members of the family include AP-1 transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
Molecular Function: DNA binding; leucine zipper domain binding; protein binding; protein C-terminus binding; protein heterodimerization activity; sequence-specific DNA binding; transcription factor activity
Biological Process: amino acid metabolic process; cellular response to amino acid starvation; cellular response to glucose starvation; circadian regulation of gene expression; gamma-aminobutyric acid signaling pathway; gluconeogenesis; mRNA transcription from RNA polymerase II promoter; negative regulation of potassium ion transport; negative regulation of translation initiation in response to stress; positive regulation of apoptosis; positive regulation of neuron apoptosis; positive regulation of transcription from RNA polymerase I promoter; positive regulation of transcription from RNA polymerase II promoter; positive regulation of transcription, DNA-dependent; regulation of transcription, DNA-dependent; transcription from RNA polymerase II promoter
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
