CTCF
CTCF,即CCCTC結合因子,別名11-zinc finger protein、CTCFL paralog。CTCF是一種多功能轉錄因子,含有11個高度保守的鋅指結構域,能夠與DNA結合并發揮功能,如介導募集cohesin、參與X染色體失活、異染色質邊界的形成、V(D)J重組、RNA剪切、凋亡等。CTCF通過識別特定的DNA序列基序結合到染色質上,并作為錨點固定染色質環,是構建染色質三維結構的基礎。CTCF在細胞生長與增殖、系統發生以及腫瘤發生等方面都有著重要的作用。CTCF的缺失會導致多種細胞分化和組織發育缺陷,包括影響記憶和學習能力、心血管發育、血液細胞分化以及肢端發育等。CTCF通過建立細胞譜系特異染色質高級結構調控決定細胞命運基因表達的分子機制,在多種生物學程序中發揮關鍵作用。

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.
