Rabbit anti-Human SEC63 Polyclonal Antibody

Uniprot Id

Q9UGP8

Target Species

Human

Target Name

SEC63

Target Full Name

Translocation protein SEC63 homolog

Target Function

Mediates cotranslational and post-translational transport of certain precursor polypeptides across endoplasmic reticulum (ER). Proposed to play an auxiliary role in recognition of precursors with short and apolar signal peptides. May cooperate with SEC62 and HSPA5/BiP to facilitate targeting of small presecretory proteins into the SEC61 channel-forming translocon complex, triggering channel opening for polypeptide translocation to the ER lumen. Required for efficient PKD1/Polycystin-1 biogenesis and trafficking to the plasma membrane of the primary cilia.

Target Involvement

Polycystic liver disease 2 (PCLD2)

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Target Tissue Specificity

Widely expressed, with high levels in the liver.

Target Synonyms

SEC63; SEC63L; Translocation protein SEC63 homolog

Target Background

The Sec61 complex is the central component of the protein translocation apparatus of the endoplasmic reticulum (ER) membrane. The protein encoded by this gene and SEC62 protein are found to be associated with ribosome-free SEC61 complex. It is speculated that Sec61-Sec62-Sec63 may perform post-translational protein translocation into the ER. The Sec61-Sec62-Sec63 complex might also perform the backward transport of ER proteins that are subject to the ubiquitin-proteasome-dependent degradation pathway. The encoded protein is an integral membrane protein located in the rough ER.
