GCLM

Description

The GCLM (glutamate-cysteine ligase modifier subunit) is a protein-coding gene located on chromosome 1.

Glutamate-cysteine ligase regulatory subunit is an enzyme that in humans is encoded by the GCLM gene. Glutamate-cysteine ligase, also known as gamma-glutamylcysteine synthetase, is the first rate limiting enzyme of glutathione synthesis. The enzyme consists of two subunits, a heavy catalytic subunit and a light regulatory subunit. Gamma glutamylcysteine synthetase deficiency has been implicated in some forms of hemolytic anemia.

The GCLM gene encodes the regulatory subunit of glutamate-cysteine ligase (GCL), also known as gamma-glutamylcysteine synthetase. This enzyme is the rate-limiting step in the synthesis of glutathione, a crucial antioxidant. The GCLM subunit is essential for the proper function of GCL, and its deficiency can lead to hemolytic anemia.

GCLM is also known as GLCLR.
