背景
功能:组蛋白乙酰转移酶 HBO1 复合物的催化亚基,特异性地介导组蛋白 H3 在“赖氨酸-14”处的乙酰化 (H3K14ac),从而调节各种过程,如基因转录、蛋白质泛素化、免疫调节、干细胞多能性和自我更新维持以及胚胎发育 (PubMed:16387653, PubMed:21753189, PubMed:24065767, PubMed:26620551, PubMed:31767635, PubMed:31827282)。一些复合物还能催化组蛋白 H4 在“Lys-5”、“Lys-8”和“Lys-12”位点的乙酰化 (分别为 H4K5ac、H4K8ac 和 H4K12ac),从而调节 DNA 复制起始 (PubMed:10438470, PubMed:19187766, PubMed:20129055, PubMed:24065767)。 HBO1 复合物的特异性由其支架亚基决定:含有 BRPF 支架 (BRPF1、BRD1/BRPF2 或 BRPF3) 的复合物引导 KAT7/HBO1 特异性靶向 H3K14ac,而含有 JADE 支架 (JADE1、JADE2 和 JADE3) 的复合物则引导 KAT7/HBO1 特异性靶向组蛋白 H4 (PubMed:19187766, PubMed:20129055, PubMed:24065767, PubMed:26620551)。H3K14ac 通过促进 RNA 聚合酶 II 的加工性来促进转录延伸 (PubMed:31827282)。它通过与 BRD1/BRPF2 形成复合物,作为造血的关键调节因子,引导 KAT7/HBO1 特异性靶向 H3K14ac,并促进红系分化 (PubMed:21753189)。H3K14ac 也是 T 细胞发育所必需的 (基于相似性)。 KAT7/HBO1 介导的乙酰化促进 DNA 复制起始的两个连续步骤,即许可和激活:H3K14ac 促进复制起点的激活,组蛋白 H4 乙酰化 (H4K5ac、H4K8ac 和 H4K12ac) 促进 MCM 复合物的染色质加载,从而促进 DNA 复制许可 (PubMed:10438470, PubMed:11278932, PubMed:18832067, PubMed:19187766, PubMed:20129055, PubMed:21856198, PubMed:24065767, PubMed:26620551)。作为着丝粒 CENPA 组装的正调控因子:被募集至着丝粒并介导组蛋白乙酰化,从而阻止 SUV39H1 介导的着丝粒失活,这可能是通过增加组蛋白的周转/交换实现的 (PubMed:27270040)。参与核苷酸切除修复:紫外线照射后,ATR 对其磷酸化,促进其定位至 DNA 损伤位点,并在该位点介导组蛋白乙酰化,从而促进 XPC 募集至受损 DNA 位点 (PubMed:28719581)。作为 NF-κB 抑制剂,其作用独立于其组蛋白乙酰转移酶活性 (PubMed:16997280);在急性髓系白血病 (AML) 中,对白血病干细胞的维持起着核心作用 (PubMed:31827282)。通过介导组蛋白 H3 在“赖氨酸-14”(H3K14ac) 处的乙酰化发挥作用,从而促进 RNA 聚合酶 II 的加工能力,以维持关键基因 (如 HOXA9 和 HOXA10) 的高表达,这些基因有助于维持白血病干细胞的功能特性 (PubMed:31827282)。
亚细胞定位:细胞核;染色体;着丝粒染色体;细胞质;胞质溶胶
表达水平:
组织特异性:普遍表达,在睾丸中表达水平最高
异构体 & 翻译后修饰:O95251 有 5 种异构体:O95251-1:70642 Da (预测值);O95251-2:58136 Da (预测值);O95251-3:51440 Da (预测值);O95251-4:66947 Da (预测值);O95251-5:55135 Da (预测值)。
DNA 损伤后,ATR 可磷酸化 O95251 的 Ser-50 和 Ser-53 位点,促进其被 CRL4 (DDB2) 复合物泛素化并随后降解 (PubMed:26572825)。紫外线诱导的 DNA 损伤后,ATR 也可磷酸化 O95251 的 Ser-50 和 Ser-53 位点,促进其定位至 DNA 损伤位点 (PubMed:28719581)。 PLK1 在有丝分裂期间对 Ser-57 位点的磷酸化似乎对复制前复合物的形成和 DNA 复制许可至关重要,并且需要 CDK1 预先对 Thr-85 和 Thr-88 位点的磷酸化 (PubMed:18250300)。MAP2K1 可对其进行磷酸化,从而加速其降解 (基于相似性);Lys-338 位点的泛素化会导致蛋白酶体降解 (PubMed:23319590)。CRL4 (DDB2) 复合物在 ATR 磷酸化后对其进行泛素化,导致其后续降解 (PubMed:26572825);Lys-432 位点的自身乙酰化是其正常功能所必需的。
亚基:由 KAT7/HBO1、MEAF6、ING4 或 ING5 以及一个支架亚基组成的 HBO1 复合物的组成部分:含有 BRPF 支架 (BRPF1、BRD1/BRPF2 或 BRPF3) 的复合物将 KAT7/HBO1 的特异性导向 H3K14ac,而含有 JADE 支架 (JADE1、JADE2 和 JADE3) 的复合物介导组蛋白 H4 的乙酰化 (PubMed:16387653、PubMed:19187766、PubMed:20129055、PubMed:21753189、PubMed:24065767、PubMed:26620551、PubMed:29382722)。与 MCM2 和 ORC1 相互作用 (PubMed:10438470、PubMed:11278932、PubMed:16387653)。在二氢睾酮存在下,与雄激素受体 (AR) 相互作用 (PubMed:10930412)。与 CDT1 相互作用 (PubMed:18832067)。与 MAP2K1 和 CUL1 相互作用 (基于相似性)。与 p53/TP53 相互作用,从而抑制组蛋白乙酰转移酶活性 (PubMed:17954561)。与 MIS18BP1 相互作用 (PubMed:27270040)。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
