Background

TEX264 (testis expressed gene 264) is a single-pass transmembrane protein localized to the endoplasmic reticulum (ER) that plays a key role in the clearance of damaged ER via the selective autophagic process of ER-phagy (1,2). It contains an LC3 interacting region (LIR) acting as a bridge from the ER to Atg8 family members, LC3 and GABARAP, on the autophagosome. Phosphorylation of TEX264 by casein kinase 2 can enhance its interaction with Atg8 family members (3). TEX264-mediated ER-phagy has been observed in pathological conditions, including acetaminophen-induced hepatotoxicity and in neuroinflammation associated with Alzheimer’s Disease (4,5). TEX264 has also been found to contribute to genomic stability through association with the VCP ATPase promoting TOP1-mediated DNA repair (6).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

TEX264 (E2J3J) Rabbit mAb

Western Blotting Image 1: TEX264 (E2J3J) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using TEX264 (E2J3J) Rabbit mAb (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Low expression of TEX264 protein in HCC1806 cells is consistent with the predicted expression pattern.
Western Blotting Image 2: TEX264 (E2J3J) Rabbit mAb Expand Image
Western blot analysis of extracts from 293T cells, mock transfected (-) or transiently transfected with plasmid expressing Myc/DDK-tagged human TEX264 protein (hTEX264-Myc/DDK; +), using TEX264 (E2J3J) Rabbit mAb (upper), Myc-Tag (71D10) Rabbit mAb #2278 (middle), or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower).
Immunoprecipitation Image 1: TEX264 (E2J3J) Rabbit mAb Expand Image
Immunoprecipitation of TEX264 protein from OCI-AML3 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is TEX264 (E2J3J) Rabbit mAb. Western blot analysis was performed using TEX264 (E2J3J) Rabbit mAb. Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 was used as a secondary antibody.
