CAPN3

Musculoskeletal System · Skeletal Muscle Sarcomere Structure

How do muscle fibers remove damaged proteins from their contractile machinery?

CAPN3 makes calpain-3, an enzyme that cuts selected proteins within muscle sarcomeres. Removing damaged components helps maintain the structures used for contraction.

Common Gene Name
