產(chǎn)品介紹 |
HP1 alpha is a component of heterochromatin. It recognizes and binds histone H3 tails methylated at Lys-9, leading to epigenetic repression. HP1 alpha may interact with lamin B receptor (LBR). This interaction can contribute to the association of the heterochromatin with the inner nuclear membrane. HP1 proteins are relatively small proteins (~25 kDa) with a conserved amino-terminal chromo domain and a structurally related carboxy-terminal motif, the chromo shadow domain. Both domains of HP1 are required for binding to native chromatin in vivo, but they contribute differentially to binding in euchromatin and heterochromatin. SWISS: P05205 Gene ID: N/A Database links: GenBank: ACI96782.1 異染色質(zhì)蛋白1(Heterochromatin protein 1 (HP1))一般認(rèn)為是異染色質(zhì)的維持者,異染色質(zhì)是轉(zhuǎn)錄沉默的固縮DNA,常常與中心粒等區(qū)域有關(guān)。這種固縮的DNA被認(rèn)為是轉(zhuǎn)錄因子無法接近的,但近期的Science上發(fā)表的兩篇報道對這個觀點提出了挑戰(zhàn)。 這個新的研究提出HP1可能是異染色質(zhì)活性調(diào)控的重要因子,在細(xì)胞生理活動中具有的重要功能。 |
