Its molecular weight is approximately 20 kDa. The protein is expressed in various tissues with particularly high expression in the liver and heart. PC4 facilitates transcription by interacting with basal transcription factors. It bonds with single-stranded DNA enhancing RNA polymerase II's ability to start transcription.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nMany experts note PC4's significant role in transcriptional regulation and chromatin structure dynamics. It operates as part of a multifunctional complex that regulates gene expression. PC4 stabilizes transcriptional pre-initiation complexes which helps initiate gene transcription. Its capacity to modulate chromatin can also impact DNA repair and replication processes emphasizing its diverse roles beyond transcriptional activation.\u003cbr\u003e\nPathways\u003cbr\u003e\nTranscription regulation processes often feature PC4 prominently. It interacts within the transcriptional machinery alongside proteins such as TFIIB and TFIIH. Additionally PC4 participates in chromatin remodeling pathways which affect DNA accessibility and gene transcription. This protein's interaction with other transcription factors establishes it as a versatile component in gene expression pathways.\u003cbr\u003e\nResearchers link PC4 to cancer and cardiac hypertrophy. In cancer PC4 can influence oncogene activation and tumor suppressor pathways interacting with proteins like p53 in these contexts. Studies also suggest PC4 involvement in cardiac hypertrophy by affecting genes associated with heart muscle enlargement where it functions alongside other cardiac stress-responsive proteins. These associations highlight PC4's potential as a therapeutic target in various pathologies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46844022849705,"sku":"ab95890","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab95890","provider":"Iright","version":"1.0","type":"link"}
