Angiotensin
Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system which is a major target for drugs that […]
Prostate-specific antigen
Prostate-specific antigen (PSA) also known as gamma-seminoprotein or kallikrein-3 (KLK3) is a glycoprotein enzyme encoded in humans by the KLK3 gene. PSA is a member of the kallikrein-related peptidase family […]
Renin
Renin (/ˈriːnɨn/ REE-nin) also known as an angiotensinogenase is an enzyme that participates in the body’s renin-angiotensin system (RAS)—also known as the renin-angiotensin-aldosterone axis—that mediates extracellular volume (i.e. that of […]
Alanine transaminase
Alanine transaminase or ALT is a transaminase enzyme (EC 2.6.1.2). It is also called serum glutamic-pyruvic transaminase (SGPT) or alanine aminotransferase (ALAT).ALT is found in plasma and in various bodily […]
Rhodopsin
Rhodopsin also known as visual purple is a biological pigment in photoreceptor cells of the retina that is responsible for the first events in the perception of light. Rhodopsins belong […]
Proinsulin
Proinsulin is the prohormone precursor to insulin made in the beta cells of the islets of Langerhans specialized regions of the pancreas. In humans proinsulin is encoded by the INS […]
Glucagon
Glucagon is a peptide hormone produced by alpha cells of the pancreas that raises blood glucose levels. Its effect is opposite that of insulin which lowers blood glucose levels. The […]
Luteinizing hormone
Luteinizing hormone (LH also known as lutropin and sometimes lutrophin) is a hormone produced by gonadotroph cells in the anterior pituitary gland. In females an acute rise of LH (LH […]
CD32
CD32 is a surface receptor protein and part of a large population of B cell co-receptors which act to modulate signaling.It has a low-affinity for IgG antibodies and down-regulates antibody […]
