Detection of Human alpha ‑Taxilin by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and HEK293 human embryonic kidney cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human alpha ‑Taxilin Monoclonal Antibody (Catalog # MAB5575) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for alpha ‑Taxilin at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

alpha ‑Taxilin (TXLN‑ alpha ; also p75 [in rat] and IL‑14 alpha ) is the founding member of the taxilin family of proteins. Although its predicted MW is 62 kDa, it runs anomalously at 74‑76 kDa in SDS‑PAGE. alpha ‑Taxilin is ubiquitously expressed and participates in intracellular vesicle trafficking. In particular, alpha ‑Taxilin interacts with syntaxin family members that localize to the plasma membrane, providing for SNARE complex formation. alpha ‑Taxilin also regulates the placement of growing protein chains. Human alpha ‑Taxilin is 546 amino acids (aa) in length. Its defining characteristic is a large coiled‑coil region between aa 186‑491. When an alternate start site at Met176 is used, a secreted cytokine is generated termed IL‑14 alpha. Over aa 1‑162, human alpha ‑Taxilin shares 81% aa identity with mouse alpha ‑Taxilin.
