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. Gene ID: Fruit Fly HP1 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。 |
