CC -!- PTM: Undergoes calcium-induced successive autoproteolytic cleavages
CC that generate a membrane-bound 78 kDa active form and an intracellular
CC 75 kDa active form. Calpastatin reduces with high efficiency the
CC transition from 78 kDa to 75 kDa calpain forms.
CC {ECO:0000269|PubMed:8769305, ECO:0000269|PubMed:8954105}.
CC -!- DISEASE: Spastic paraplegia 76, autosomal recessive (SPG76)
CC [MIM:616907]: A form of spastic paraplegia, a neurodegenerative
CC disorder characterized by a slow, gradual, progressive weakness and
CC spasticity of the lower limbs. Rate of progression and the severity of
CC symptoms are quite variable. Initial symptoms may include difficulty
CC with balance, weakness and stiffness in the legs, muscle spasms, and
CC dragging the toes when walking. In some forms of the disorder, bladder
CC symptoms (such as incontinence) may appear, or the weakness and
CC stiffness may spread to other parts of the body.
CC {ECO:0000269|PubMed:27153400}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the peptidase C2 family. {ECO:0000305}.
