UBL4A is a component of the BAT3 complex, a multiprotein complex involved in the post-translational delivery of tail-anchored (TA) membrane proteins to the endoplasmic reticulum membrane. UBL4A is the TA membrane proteins, also named type II transmembrane proteins, contain a single C-terminal transmembrane region. The complex acts by facilitating TA proteins capture by ASNA1/TRC40: it is recruited to ribosomes synthesizing membrane proteins, interacts with the transmembrane region of newly released TA proteins, and transfers them to ASNA1/TRC40 for targeting. Synonyms: Polyclonal UBL4A antibody, Anti-UBL4A antibody, ubiquitin-like 4A antibody, DX254E antibody, DXS254E antibody, G6PD antibody, GDX antibody, UBL4 antibody.
