Scientific Data Images for TMEM49 Antibody - BSA Free

Western Blot: TMEM49 AntibodyBSA Free [NBP2-78784]

Western Blot: TMEM49 AntibodyBSA Free [NBP2-78784]

Western Blot: TMEM49 Antibody [NBP2-78784] - Total protein from human U2OS, HeLa, MCF7 and mouse 3T3 cell lines was separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2.0 ug/ml anti-TMEM49 in block buffer and detected with an anti-rabbit HRP secondary antibody using West Pico PLUS chemiluminescence detection reagent.

Immunocytochemistry/ Immunofluorescence: TMEM49 Antibody - BSA Free [NBP2-78784]

Immunocytochemistry/Immunofluorescence: TMEM49 Antibody [NBP2-78784] - HeLa cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X PBS + 0.05% Triton-X100. The cells were incubated with anti-TMEM49 at 10 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:500 dilution. Alpha tubulin (DM1A) NB100-690 was used as a co-stain at a 1:1000 dilution and detected with an anti-mouse Dylight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

Immunohistochemistry-Paraffin: TMEM49 Antibody - BSA Free [NBP2-78784]

Immunohistochemistry-Paraffin: TMEM49 Antibody [NBP2-78784] - Analysis of a FFPE tissue section of the human testis using 1:200 dilution of TMEM49 antibody (NBP2-78784). The signal was developed using HRP-DAB method which followed counterstaining of the cells with hematoxylin. The antibody generated mainly strong cytoplasmic staining in cytoplasm and membrane in seminiferous tubules.

Background: TMEM49

Transmembrane protein 49 (TMEM49), also known as vacuole membrane protein 1 (VMP1), is an endoplasmic reticulum (ER)-localized protein that plays an important role in autophagy and, specifically, autophagosome formation (1). TMEM49/VMP1 is synthesized as 406 amino acid (aa) transmembrane protein containing a VTT (VMP1-TMEM41b-TVP38) domain and with a theoretical molecular weight of 46 kDa (1,2). TMEM49 helps regulate ER contacts with membranes such as isolation membranes, mitochondria, endosomes, and lipid droplets (1). TMEM49/VMP1 deficiency leads to tighter ER contacts and, in the context of autophagy, results in failure of the autophagosome and lysosome to fuse and eventual disruption of autophagic flux (1).

TMEM49/VMP1 was first implicated in pancreatitis and its overexpression, together with KRAS oncogene activation, leads to development of pancreatic ductal adenocarcinoma (PDAC) (3). Aside from pancreatitis, TMEM49/VMP1 is also associated with a number of other pathologies including cancer, inflammatory bowel disease, and, potentially, neurodegenerative disorders such as Parkinson's Disease (PD) and Alzheimer's Disease (AD) (1). It is suggested that TMEM49/VMP1 deficiency in neurons results in disrupted autophagy and protein aggregation, increased ER-membrane contacts, and dysfunctional mitochondrial homeostasis, all of which contribute to neurodegeneration (1).
