cystatinlike
Cystatinlike is a gene and a protein family that shares structural similarities with cystatins. Cystatins are a class of endogenous cysteine protease inhibitors. The cystatinlike family, however, often lacks the inhibitory function typically associated with cystatins. The exact biological roles of cystatinlike proteins are not fully understood and can vary significantly between family members. Some may act as structural proteins, while others might have regulatory functions or even possess novel activities unrelated to protease inhibition.
The cystatinlike genes are found in various species, including humans and other mammals. Their discovery and
