Scientific Data Images for Human TMED1 Antibody

Detection of Human TMED1 antibody by Western Blot.

Detection of Human TMED1 by Western Blot.

Western blot shows lysates of U-87 MG human glioblastoma/astrocytoma cell line, HDLM-2 human Hodgkin's lymphoma cell line, RT-4 human bladder carcinoma cell line, and PC-3 human prostate cancer cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human TMED1 Monoclonal Antibody (Catalog # MAB22431) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for TMED1 at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of TMED1 in HEK293 Human Cell Line Transfected with Human TMED1 and eGFP by Flow Cytometry.

HEK293 human embryonic kidney cell line transfected with either (A) human TMED1 or (B) irrelevant protein and eGFP was stained with Mouse Anti-Human TMED1 Monoclonal Antibody (Catalog # MAB22431) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (F0101B). Quadrant markers were set based on control antibody staining (MAB002). View our protocol for Staining Membrane-associated Proteins.

Background: TMED1

TMED1 (Transmembrane Emp24 domain-containing protein 1) is a member of the TMED family of proteins (gene name TMED1). The TMED family of proteins are localized to membranes of the early secretory pathway, including the endoplasmic reticulum and Golgi, and function in vesicular protein trafficking (1, 2). TMED1 is a 59 kDa monomer and has been reported to exist as homodimer (3). TMED1 is composed of a 23 amino acid (aa) signal sequence, a 171 aa extra cellular domain, a 21 aa transmembrane domain, and a 12 aa cytoplasmic domain. The extracellular domain contains an 83 aa GOLD (Golgi Dynamics) domain, and COPI and COPII binding motifs are found in the cytoplasmic domain (1-3, 5). Human TMED1 shares 97% sequence identity with mouse, bovine, and rat homologs within the 171 aa extracellular domain. The beta-strand-rich GOLD domain has been specifically identified to be involved in intracellular protein trafficking (1, 4, 5). TMED1 is important in regulating innate immune signaling through its interaction with ST2L. Specifically, the GOLD domain in TMED1 interacts with the TIR domain of ST2L, a receptor for IL-33 (1). This interaction promotes ST2L association with IL-33, allowing downstream signaling cascade activating MAP kinases, p38, and JNK (1, 6). Studies have shown knockdown of TMED-1 in HUVECs impairs the IL-33 induced response resulting in reduction of IL-6 and IL-8 productions (1).
