Description

A normal glycoprotein (mucoprotein) which is not derived from plasma, but is produced by the ascending limb of the loop of Henle. When this protein is concentrated at low pH, it forms gel. Tamm-Horsfall is the most abundant protein in mammalian urine.

The protein was first purified by Tamm and Horsfall from healthy individuals. It was later detected in the urine of mammals studied.
