SEC61A1 encodes the Sec61 alpha 1 subunit, a core component of the SEC61 translocon complex. Also known as SEC61A or HSPC016, this protein forms the central channel in the endoplasmic reticulum (ER) membrane, facilitating cotranslational translocation of nascent polypeptides into the ER lumen for folding and post-translational modification, critical for ER protein homeostasis.
Dysregulation of SEC61A1 triggers unfolded protein response (UPR) and ER stress, linking to hereditary spastic paraplegia (HSP) and neurodegenerative diseases. Emerging research explores small-molecule inhibitors targeting the SEC61 translocon to correct aberrant protein trafficking; preclinical studies show promise, though clinical development remains in early stages.

IHC image of CSB-RA293494A0HU diluted at 1:100 and staining in paraffin-embedded human colorectal cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
Immunofluorescence staining of Hela cell with CSB-RA293494A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Overlay Peak curve showing HepG2 cells stained with CSB-RA293494A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
