Human Mucin-1 / MUC-1 (1036-1155) Protein, His Tag

分子別名（Synonym）

Mucin-1,MUC-1,CD227

表達區(qū)間及表達系統(tǒng)（Source）

Human Mucin-1 (1036-1155), His Tag (MU1-H52H5) is expressed from human 293 cells (HEK293). It contains AA Leu 1036 - Gly 1155 (Accession # P15941-1).

Predicted N-terminus: Leu 1036 (partial α chain) & Ser 1098 (partial β chain)

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus. The mature form of Mucin-1 is a non-covalent heterodimeric complex with the proteolytically cleaved partial α and partial β chain. Each partial α and partial β chain has a calculated MW of 7.2 kDa (partial α chain) and 8.2 kDa (partial β chain). The protein migrates as 13-15 kDa (partial α chain) and 10 kDa (partial β chain) under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>90% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）

Mucin-1蛋白在上皮細胞中具有多種功能，包括細胞保護、轉(zhuǎn)移過程中的外滲、管腔結(jié)構(gòu)的維持和信號轉(zhuǎn)導(dǎo)。MUC17含有一個延伸的、重復(fù)的細胞外糖基化結(jié)構(gòu)域和一個羧基末端，具有兩個EGF樣結(jié)構(gòu)域，一個SEA模塊結(jié)構(gòu)域、一個跨膜結(jié)構(gòu)域和具有潛在絲氨酸和酪氨酸磷酸化位點的細胞質(zhì)結(jié)構(gòu)域。通過其C末端與PDZK1相互作用，這種相互作用對正確定位很重要?？赡茉诰S持粘膜表面的穩(wěn)態(tài)方面發(fā)揮作用。
