The production of the ITGB1 recombinant monoclonal antibody involves the utilization of DNA recombinant technology and in vitro genetic manipulation. The process begins by immunizing an animal with a synthesized peptide derived from human ITGB1, followed by the isolation and selection of positive B cells. Screening and single clone identification are performed to ensure the desired antibody specificity. The light and heavy chains of the ITGB1 antibody are then amplified using PCR and integrated into a plasmid vector to create a recombinant vector. This vector is subsequently introduced into a host cell line to facilitate antibody expression. The ITGB1 recombinant monoclonal antibody is purified from the cell culture supernatant using affinity chromatography. With its capability to selectively bind to human ITGB1 protein, this antibody is highly recommended for five applications, including ELISA, WB, IHC, IF, and FC.

The ITGB1 protein is a transmembrane protein that is involved in cell adhesion, migration, proliferation, differentiation, and signaling. It forms a heterodimeric complex with different alpha integrin subunits to form functional receptors for extracellular matrix (ECM) molecules such as fibronectin, laminin, and collagen. The ITGB1 receptor is involved in a wide range of physiological and pathological processes, including embryonic development, wound healing, immune response, and cancer metastasis. Dysregulation of ITGB1 signaling has been implicated in various diseases, including cardiovascular disease, inflammation, and cancer.

Target Background

Integrins alpha-1/beta-1, alpha-2/beta-1, alpha-10/beta-1 and alpha-11/beta-1 are receptors for collagen. Integrins alpha-1/beta-1 and alpha-2/beta-2 recognize the proline-hydroxylated sequence G-F-P-G-E-R in collagen. Integrins alpha-2/beta-1, alpha-3/beta-1, alpha-4/beta-1, alpha-5/beta-1, alpha-8/beta-1, alpha-10/beta-1, alpha-11/beta-1 and alpha-V/beta-1 are receptors for fibronectin. Alpha-4/beta-1 recognizes one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. Integrin alpha-5/beta-1 is a receptor for fibrinogen. Integrin alpha-1/beta-1, alpha-2/beta-1, alpha-6/beta-1 and alpha-7/beta-1 are receptors for lamimin. Integrin alpha-6/beta-1 (ITGA6:ITGB1) is present in oocytes and is involved in sperm-egg fusion. Integrin alpha-4/beta-1 is a receptor for VCAM1. It recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-9/beta-1 is a receptor for VCAM1, cytotactin and osteopontin. It recognizes the sequence A-E-I-D-G-I-E-L in cytotactin. Integrin alpha-3/beta-1 is a receptor for epiligrin, thrombospondin and CSPG4. Alpha-3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration. Integrin alpha-V/beta-1 is a receptor for vitronectin. Beta-1 integrins recognize the sequence R-G-D in a wide array of ligands. When associated with alpha-7 integrin, regulates cell adhesion and laminin matrix deposition. Involved in promoting endothelial cell motility and angiogenesis. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process and the formation of mineralized bone nodules. May be involved in up-regulation of the activity of kinases such as PKC via binding to KRT1. Together with KRT1 and RACK1, serves as a platform for SRC activation or inactivation. Plays a mechanistic adhesive role during telophase, required for the successful completion of cytokinesis. Integrin alpha-3/beta-1 provides a docking site for FAP (seprase) at invadopodia plasma membranes in a collagen-dependent manner and hence may participate in the adhesion, formation of invadopodia and matrix degradation processes, promoting cell invasion. ITGA4:ITGB1 binds to fractalkine (CX3CL1) and may act as its coreceptor in CX3CR1-dependent fractalkine signaling. ITGA4:ITGB1 and ITGA5:ITGB1 bind to PLA2G2A via a site (site 2) which is distinct from the classical ligand-binding site (site 1) and this induces integrin conformational changes and enhanced ligand binding to site 1. ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-D-dependent cell adhesion to FBN1. ITGA5:ITGB1 is a receptor for IL1B and binding is essential for IL1B signaling. ITGA5:ITGB3 is a receptor for soluble CD40LG and is required for CD40/CD40LG signaling.; Interferes with isoform 1 resulting in a dominant negative effect on cell adhesion and migration (in vitro).; Isoform 5 displaces isoform 1 in striated muscles.; (Microbial infection) Integrin ITGA2:ITGB1 acts as a receptor for Human echoviruses 1 and 8.; (Microbial infection) Acts as a receptor for Cytomegalovirus/HHV-5.; (Microbial infection) Acts as a receptor for Epstein-Barr virus/HHV-4.; (Microbial infection) Integrin ITGA5:ITGB1 acts as a receptor for Human parvovirus B19.; (Microbial infection) Integrin ITGA2:ITGB1 acts as a receptor for Human rotavirus.; (Microbial infection) Acts as a receptor for Mammalian reovirus.; (Microbial infection) In case of HIV-1 infection, integrin ITGA5:ITGB1 binding to extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions.; (Microbial infection) Interacts with CotH proteins expressed by fungi of the order mucorales, the causative agent of mucormycosis, which plays an important role in epithelial cell invasion by the fungi. Integrin ITGA3:ITGB1 may act as a receptor for R.delemar CotH7 in alveolar epithelial cells, which may be an early step in pulmonary mucormycosis disease progression.
