Identification
HMDB Protein ID CDBP02770
Secondary Accession Numbers Not Available
Name Calsequestrin-1
Description Not Available
Synonyms
  1. Calmitin
  2. Calsequestrin, skeletal muscle isoform
Gene Name CASQ1
Protein Type Metal Binding
Biological Properties
General Function Involved in calcium ion binding
Specific Function Calsequestrin is a high-capacity, moderate affinity, calcium-binding protein and thus acts as an internal calcium store in muscle. The release of calcium bound to calsequestrin through a calcium release channel triggers muscle contraction. Binds 40 to 50 moles of calcium. Also binds laminin
