Sarcalumenin is a calcium-binding protein that can be found in the sarcoplasmic reticulum of striated muscle. Sarcalumenin is partially responsible for calcium buffering in the lumen of the sarcoplasmic reticulum and helps out calcium pump proteins.
Sarcalumenin is a protein found in striated muscle that regulates calcium ion movement within the sarcoplasmic reticulum. It assists proteins responsible for pumping calcium ions out of the cell, which helps control muscle contraction and relaxation.
