|Product Overview:||Recombinant Human ADAM28(Leu72 & Leu191-Ala623) fused with His tag at C-terminal was expressed in CHO.|
|Description:||A distintegrin and metalloprotease domain-containing protein 28 (ADAM28), also known as MDC-L, is a member of the M12B peptidase family of enzymes. It is synthesized as an approximately 80-90 kDa glycosylated proprotein that is processed to a mature form later in the secretory pathway. After the removal of the propeptide that contains a cysteine switch motif, the activated form of ADAM28 consists of a 467 aa extracellular domain (ECD) which contains a peptidase, disintegrin, cysteine-rich and EGF-like domains, followed by a 21 aa transmembrane segment and an 89 aa cytoplasmic domain. Alternative splicing generates additional isoforms with a variety of substitutions and deletions in the cysteine-rich and EGF-like domains. Within the ECD, human ADAM28 shares 73% aa sequence identity with mouse and rat ADAM28. ADAM28 is a cell surface protein that is involved in a variety of cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis, and exhibits catalytic activity to insulin-like growth factor binding protein-3. Like many members of the ADAM proteins, the disintegrin domain of ADAM28 interacts with integrin to influence cell adhesion and cell-cell interaction. ADAM28 can mediate the adhesion of the Jurkat cells, T-lymphoma cell line, through integrin alpha 4b1(9). R&D Systems in-house testing also indicates that ADAM28 cleaves IGFBP-3.|
