PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N-terminal domain (N-(1-103)) binds to a 413-kDa TRIM-like protein, myospryn (CMYA5) with a repetitive, acidic N-terminal part
  • a FN3 domain and the SPRY domain are needed for titin M10 binding
  • C terminus with BBC, FN3, and SPRY domains in a configuration reminiscent of the tripartite motif protein family, as well as the dysbindin-binding site and a region mediating self-association
  • and a domain structure related to the tripartite motif proteins

    text
  • sarcoplasmic reticulum
  • localized to the costamere
  • characterization of CMYA5 and XIRP2 revealed localization of their protein products to the muscle costamere
  • basic FUNCTION
  • Z-disc-related protein, costameric protein functioning as a muscle-specific protein kinase A (PKA) anchoring protein or AKAP1
  • functions directly downstream of MEF2A at the costamere in striated muscle potentially playing a role in myofibrillogenesis
  • having ability to anchor AKAP1 at the costamere (may have profound regulatory implications given that dystrophin has been shown to be phosphorylated by AKAP1)
  • muscle-specific protein which function in vesicular trafficking and protein kinase A signaling and implicated in the pathogenesis of Duchenne muscular dystrophy

    protein
  • binding to dysbindin
  • direct molecular interactions of myospryn with the M-band part of the sarcomeric protein titin and with the skeletal muscle-specific protease calpain 3
  • XIRP2 and CMYA5 are MEF2A-dependent genes that encode costamere-localized proteins
