Inter-alpha-inhibitor, also known as serine protease inhibitor Kazal type (SPINT), is a group of proteins that play a crucial role in regulating the activity of serine proteases, enzymes involved in various physiological processes such as blood clotting, inflammation, and tissue remodeling. These proteins are composed of multiple identical subunits, which are held together by disulfide bonds, forming a complex structure that allows them to bind and inhibit the activity of their target proteases. Inter-alpha-inhibitor proteins are found in various body fluids, including blood, urine, and synovial fluid, and their levels can be altered in certain pathological conditions, such as cancer, inflammation, and kidney disease. Understanding the function and regulation of inter-alpha-inhibitor proteins is essential for developing therapeutic strategies targeting serine protease-mediated diseases.
The CAS Registry Mumber 393-46-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 3 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 393-46: (5*3)+(4*9)+(3*3)+(2*4)+(1*6)=74 74 % 10 = 4 So 393-46-4 is a valid CAS Registry Number.
