Rabbit anti-Human OS9 Polyclonal Antibody

Uniprot Id

Q13438

Target Species

Human

Target Name

OS9

Target Full Name

Protein OS-9

Target Function

Lectin which functions in endoplasmic reticulum (ER) quality control and ER-associated degradation (ERAD). May bind terminally misfolded non-glycosylated proteins as well as improperly folded glycoproteins, retain them in the ER, and possibly transfer them to the ubiquitination machinery and promote their degradation. Possible targets include TRPV4.

Target Subcellular Location

Endoplasmic reticulum lumen.

Target Protein Families

OS-9 family

Target Tissue Specificity

Ubiquitously expressed. Found as well in all tumor cell lines analyzed, amplified in sarcomas. Highly expressed in osteosarcoma SJSA-1 and rhabdomyosarcoma Rh30 cell lines. Isoform 2 is the major isoform detected in all cell types examined.

Target Synonyms

Amplified in osteosarcoma 9; amplified in osteosarcoma; ERLEC2; OS-9 ; Os9; OS9_HUMAN; Osteosarcoma amplified 9 endoplasmic reticulum lectin; Protein OS-9

Target Background

This gene encodes a protein that is highly expressed in osteosarcomas. This protein binds to the hypoxia-inducible factor 1 (HIF-1), a key regulator of the hypoxic response and angiogenesis, and promotes the degradation of one of its subunits. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
