Related Product Information for anti-COL18A1 antibody
Description: This gene encodes the alpha chain of type XVIII collagen. This collagen is one of the multiplexins, extracellular matrix proteins that contain multiple triple-helix domains (collagenous domains) interrupted by non-collagenous domains. The proteolytically produced C-terminal fragment of type XVIII collagen is endostatin, a potent antiangiogenic protein. Mutations in this gene are associated with Knobloch syndrome. The main features of this syndrome involve retinal abnormalities, so type XVIII collagen may play an important role in retinal structure and in neural tube closure. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]
Function: Probably plays a major role in determining the retinal structure as well as in the closure of the neural tube.
Subunit Structure: Non-collagenous domain 1 forms homotrimers. Endostatin is monomeric (PubMed:11257123). Recombinant non-collagenous domain 1 has stronger affinity to NID1, HSPG2 and laminin-1:NID1 complex and lower affinity to FBLN1 and FBLN2 than endostatin. Endostatin interacts with KDR/VEGFR2. Endostatin interacts with the ITGA5:ITGB1 complex (By similarity).
Post-translational Modifications: Prolines at the third position of the tripeptide repeating unit (G-X-Y) of the triple-helical regions are hydroxylated. Circulating endostatins are found as sialoglycoprotein and asialoglycoprotein structures. Undergoes proteolytic processing by cathepsin-L and elastase-like proteases to generate both NC1 trimers and endostatin monomers (PubMed:10626789). In vitro, several proteolytic cleavage sites in the non-collagenous domain 1 hinge region generating different endostatin-like peptides are reported (By similarity).
Similarity: Belongs to the multiplexin collagen family.

NCBI Description

This gene encodes the alpha chain of type XVIII collagen. This collagen is one of the multiplexins, extracellular matrix proteins that contain multiple triple-helix domains (collagenous domains) interrupted by non-collagenous domains. A long isoform of the protein has an N-terminal domain that is homologous to the extracellular part of frizzled receptors. Proteolytic processing at several endogenous cleavage sites in the C-terminal domain results in production of endostatin, a potent antiangiogenic protein that is able to inhibit angiogenesis and tumor growth. Mutations in this gene are associated with Knobloch syndrome. The main features of this syndrome involve retinal abnormalities, so type XVIII collagen may play an important role in retinal structure and in neural tube closure. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

Uniprot Description

Product Notes

The COL18A1 col18a1 (Catalog #AAA9607232) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The COL18A1 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's COL18A1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemisty (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (EIA). WB: 1:500-1:2000 IHC: 1:50-1:200 IF/ICC: 1:100-1:500. Researchers should empirically determine the suitability of the COL18A1 col18a1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "COL18A1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
