receptors, which include three different types (1, 2, 3) generated
by alternative splicing of this gene. These receptors or isoforms
are macrophage-specific trimeric integral membrane glycoproteins
and have been implicated in many macrophage-associated
physiological and pathological processes including atherosclerosis,
Alzheimer's disease, and host defense. The isoforms type 1 and type
2 are functional receptors and are able to mediate the endocytosis
of modified low density lipoproteins (LDLs). The isoform type 3
does not internalize modified LDL (acetyl-LDL) despite having the
domain shown to mediate this function in the types 1 and 2
isoforms. It has an altered intracellular processing and is trapped
within the endoplasmic reticulum, making it unable to perform
endocytosis. The isoform type 3 can inhibit the function of
isoforms type 1 and type 2 when co-expressed, indicating a dominant
negative effect and suggesting a mechanism for regulation of
scavenger receptor activity in macrophages.

Uniprot Description
MSR1: Membrane glycoproteins implicated in the pathologic deposition of cholesterol in arterial walls during atherogenesis. Two types of receptor subunits exist. These receptors mediate the endocytosis of a diverse group of macromolecules, including modified low density lipoproteins (LDL). Isoform III does not internalize actetylated LDL. Defects in MSR1 may be a cause of prostate cancer (PC). A malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet- ring cell carcinoma and neuroendocrine carcinoma. MSR1 variants may play a role in susceptibility to prostate cancer. MSR1 variants have been found in individuals with prostate cancer and co-segregate with the disease in some families. Defects in MSR1 may be a cause of Barrett esophagus (BE). A condition characterized by a metaplastic change in which normal esophageal squamous epithelium is replaced by a columnar and intestinal-type epithelium. Patients with Barrett esophagus have an increased risk of esophageal adenocarcinoma. The main cause of Barrett esophagus is gastroesophageal reflux. The retrograde movement of acid and bile salts from the stomach into the esophagus causes prolonged injury to the esophageal epithelium and induces chronic esophagitis, which in turn is believed to trigger the pathologic changes. Genetic variants in MSR1 have been found in individuals with Barrett esophagus and are thought to contribute to disease susceptibility. 3 isoforms of the human protein are produced by alternative splicing.

Product Notes
The MSR1 msr1 (Catalog #AAA9210047) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 336-364. The MSR1 Antibody (C-term) reacts with Human, mouse (Predicted Reactivity: Bovine) and may cross-react with other species as described in the data sheet. AAA Biotech's MSR1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). WB~~1:1000. Researchers should empirically determine the suitability of the MSR1 msr1 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 "MSR1, 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.Precautions
