Recombinant Human HLA-DOB, His-tagged

• Cat.No.: HLA-DOB-190H
• Product Overview: HLA-DOB, 27-224aa, Human, His tag, E.coli

Specification

• Species: Human

• Description: HLA-DOB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DOA) and a beta chain (DOB), both anchored in the membrane. It is located in intracellular vesicles. DO suppresses peptide loading of MHC class II molecules by inhibiting HLA-DM. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Recombinant human HLA-DOB protein, fused to His-tag at N-terminus, was expressed in E.coli.
