CTCF
CTCF，即CCCTC結(jié)合因子，別名11-zinc finger protein、CTCFL paralog。CTCF是一種多功能轉(zhuǎn)錄因子，含有11個高度保守的鋅指結(jié)構(gòu)域，能夠與DNA結(jié)合并發(fā)揮功能，如介導(dǎo)募集cohesin、參與X染色體失活、異染色質(zhì)邊界的形成、V(D)J重組、RNA剪切、凋亡等。CTCF通過識別特定的DNA序列基序結(jié)合到染色質(zhì)上，并作為錨點(diǎn)固定染色質(zhì)環(huán)，是構(gòu)建染色質(zhì)三維結(jié)構(gòu)的基礎(chǔ)。CTCF在細(xì)胞生長與增殖、系統(tǒng)發(fā)生以及腫瘤發(fā)生等方面都有著重要的作用。CTCF的缺失會導(dǎo)致多種細(xì)胞分化和組織發(fā)育缺陷，包括影響記憶和學(xué)習(xí)能力、心血管發(fā)育、血液細(xì)胞分化以及肢端發(fā)育等。CTCF通過建立細(xì)胞譜系特異染色質(zhì)高級結(jié)構(gòu)調(diào)控決定細(xì)胞命運(yùn)基因表達(dá)的分子機(jī)制，在多種生物學(xué)程序中發(fā)揮關(guān)鍵作用。

Immunohistochemistry of paraffin-embedded human ovarian cancer using CSB-PA006138DSR2HU at dilution of 1:100
Chromatin Immunoprecipitation Hela (1.2*106) were cross-linked with formaldehyde, sonicated, and immunoprecipitated with 4μg anti-CTCF or a control normal rabbit IgG. The resulting ChIP DNA was quantified using real-time PCR with primers (CSB-PP006138HU) against the H19ICR promoter.
