一般說明
SIL1 (SIL1 nucleotide exchange factor) is a glycoprotein present in the membrane of endoplasmic reticulum. It is composed of an N-terminal endoplasmic reticulum (ER) target zone, four armadillo repeats (ARMs), two N-linked glycosylation sites and a C-terminal putative ER retention tetrapeptide. It is expressed in the pancreatic β cells and helps in several activities including islet insulin content, islet sizing, glucose tolerance, and glucose-stimulated insulin secretion in vivo.

應用
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

生化／生理作用
SIL1 (SIL1 nucleotide exchange factor) is involved in β cell function. During protein folding, it binds to HSP (heat shock protein) to acts as an adenine nucleotide exchange factor. It binds to the ADP-bound HSPA5, which further facilitates ADP release as well as the release of HSPA5 from its substrates. As a result, ATP is attached with the HSPA5. Thus, SIL1 stabilizes proper folding of newly synthesized proteins and degrades those proteins that fail to mature properly. Mutations in SIL1 cause cerebellar ataxia, chronic myopathy, cataracts, delayed motor development and intellectual disability, collectively known as Marinesco-Sjögren syndrome.
特點和優勢
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

Marinesco-Sjögren syndrome is a rare autosomal recessive multisystem disorder featuring cerebellar ataxia, early-onset cataracts, chronic myopathy, variable intellectual disability and delayed motor development. More recently, mutations in the SIL1 gene, which encodes an endoplasmic reticulum resident co-chaperone, were identified as

Marinesco-Sjögren syndrome (MSS) is a rare autosomal recessively inherited disorder with mental retardation (MR). Recently, mutations in the SIL1 gene, encoding a co-chaperone which regulates the chaperone HSPA5, were identified as a major cause of MSS. We here examined the
