Disease
[MYPC1_HUMAN] Defects in MYBPC1 are the cause of arthrogryposis, distal, type 1B (DA1B) [MIM:614335]. A form of distal arthrogryposis, a disease characterized by congenital joint contractures that mainly involve two or more distal parts of the limbs, in the absence of a primary neurological or muscle disease. Distal arthrogryposis type 1 is characterized largely by camptodactyly and clubfoot. Hypoplasia and/or absence of some interphalangeal creases is common. The shoulders and hips are less frequently affected.[1] Note=Defects in MYBPC1 may be a cause of autosomal recessive lethal congenital contractural syndrome (LCCS), a severe, neonatally lethal form of arthrogryposis.[2]
Function
[MYPC1_HUMAN] Thick filament-associated protein located in the crossbridge region of vertebrate striated muscle a bands. In vitro it binds MHC, F-actin and native thin filaments, and modifies the activity of actin-activated myosin ATPase. It may modulate muscle contraction or may play a more structural role.
