L-type voltage-gated Ca2+ channels (CaV1.2 and CaV1.3, called CaV) interact with the Ca2+ sensor proteins, calmodulin (CaM) and Ca2+ binding Protein 1 (CaBP1), that oppositely control Ca2+-dependent channel activity. CaM and CaBP1 can each bind to the IQ-motif within the C-terminal cytosolic ...

Moving forward, it's essential to keep these visual contexts in mind when discussing L-Type Ca2 Channel Regulation By Calmodulin And Cabp1.
- Calmodulin (CaM) and calcium-binding protein 1 (CaBP1) are both key modulators of CaV1.2 activity. Under basal resting conditions (cytosolic Ca2+ concentration equal to 100 nM), both CaM and CaBP1 promote channel opening.
Such details provide a deeper understanding and appreciation for L-Type Ca2 Channel Regulation By Calmodulin And Cabp1.
- (A,C,E) Apo-CaBP1 with NSCaTE peptide: ITC (A), 1H15N HSQC (C) and chemical shift perturbation (E). (B,D,F) Ca2+/CaBP1 with NSCaTE peptide: ITC (B), 1H15N HSQC (D) and chemical shift perturbation (F). Please note that compared to Ca2+-CaBP1, the binding of NSCaTE to apo-CaBP1 was extremely weak as indicated by the ITC and NMR data. The ITC data show that both binding events are exothermic. ...
