Cullin-4A is a protein that in humans is encoded by the CUL4A gene. [4] [5] CUL4A belongs to the cullin family of ubiquitin ligase proteins and is highly homologous to the CUL4B protein. CUL4A regulates numerous key processes such as DNA repair, chromatin remodeling, spermatogenesis, haematopoiesis and the mitotic cell cycle.

2024年12月24日 · CUL4A (Cullin 4A) is a Protein Coding gene. Diseases associated with CUL4A include Hematologic Cancer and Xeroderma Pigmentosum, Variant Type. Among its related pathways are Transcription-Coupled Nucleotide Excision Repair (TC-NER) and DNA repair pathways, full network.

2014年2月1日 · The ability of cullin 4A (CUL4A), a scaffold protein, to recruit a repertoire of substrate adaptors allows it to assemble into distinct E3 ligase complexes to mediate turnover of key regulatory pro...

2021年11月1日 · Here we show that PHGDH was monoubiquitinated by cullin 4A-based E3 ligase complex at lysine 146 in colorectal cancer (CRC) cells, which enhanced PHGDH activity by recruiting a chaperone protein, DnaJ homolog subfamily A member 1, to promote its tetrameric formation, thereby increasing the levels of serine, glycine, and S-adenosylmethionine (SAM).

2015年11月23日 · CUL4A, a member of the CULLIN family, functions as a scaffold protein for an E3 ubiquitin ligase. It was reported that the CUL4A gene showed amplification in some human primary hepatocellular...

CUL4A Antibody detects endogenous levels of total human CUL4A protein. Human, Monkey. Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding residues surrounding Ser12 of human CUL4A. Antibodies are purified by peptide affinity chromatography.

Cullin4A (CUL4A)是泛素-蛋白酶体系统(ubiquitin-proteasome system,UPS)中泛素E3连接酶家族的重要成员之一.UPS是细胞内蛋白降解的重要途径,越来越多的证据表明CUL4A可以通过CUL4A-DDB1-E3途径调节细胞中的一些功能蛋白质,产生相应的作用.本文就CUL4A在基因组的稳定,细胞周 …

泛素化修饰在肿瘤的发生发展中具有重要作用,其中E3泛素连接酶Cullin 4A (CUL4A)能够通过与DDB1相结合而泛素化多种底物,介导其降解.目前,已经证实在多种肿瘤中均有CUL4A基因的异常表达.本文将总结有关CUL4A在人类恶性肿瘤中的相关作用及分子机制,并讨论将其作为防治肿瘤新靶点的研究进展,为进一步开展CUL4A在肿瘤发生中的研究提供参考. 百度学术集成海量学术资源，融合人工智能、深度学习、大数据分析等技术，为科研工作者提供全面快捷的学术服务。 在这 …

2006年10月15日 · We found that CUL4A–DDB1 interacts with H3 methylated mononucleosomes and peptides. Inactivation of either CUL4 or DDB1 impairs these histone modifications. However, loss of WDR5 specifically...

CUL4A is the ubiquitin Ligase component of a multimeric complex involved in the degradation of DNA damage-response proteins (Liu et al., 2009 [PubMed 19481525]). [supplied by OMIM, Oct 2009]
