表达区间及表达系统(Source)
Human Latent TGFB1, His Tag (TG1-H524x) is expressed from human 293 cells (HEK293). It contains AA Leu 30 - Ser 390 (Accession # P01137-1).
Predicted N-terminus: His
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 42.6 kDa (monomer). The protein migrates as 38-43kDa and 50 kDa (LAP) and 13 kDa (TGFB1) under reducing (R) condition (SDS-PAGE) due to glycosylation and Interchain disulfide bond.
The protein is designed as a dimer.

背景介绍
转化生长因子β1(TGFB1),亦称TGF-β1、CED、DPD1或TGFB,是转化生长因子β细胞因子超家族的多肽成员。作为一种分泌蛋白,它执行多种细胞功能,包括调控细胞生长、增殖、分化及凋亡。TGFB1蛋白有助于控制细胞的生长与分裂(增殖)、细胞成熟以执行特定功能的过程(分化)、细胞运动以及细胞的自我毁灭(凋亡)。
该蛋白遍布全身,在出生前发育、血管形成、肌肉组织与体脂发育的调控、伤口愈合以及免疫系统功能中发挥作用。TGFB1在构成骨骼的组织中尤为丰富,参与调节骨骼生长,并活跃于细胞间隙形成的复杂网络(细胞外基质)中。在细胞内,该蛋白通常处于关闭(失活)状态,直至接收到化学信号才被激活。
TGFB1在调控免疫系统中扮演重要角色,并对不同类型或不同发育阶段的细胞表现出不同的活性。大多数免疫细胞(或白细胞)都能分泌TGFB1。研究已证实,TGFB1可与TGFβ受体1、LTBP1、YWHAE、EIF3I及核心蛋白聚糖发生相互作用。
