Function

Thin filament-associated protein that is implicated in the regulation and modulation of smooth muscle contraction. It is capable of binding to actin, calmodulin and tropomyosin. The interaction of calponin with actin inhibits the actomyosin Mg-ATPase activity (By similarity).

Activity summary

Calponin 1 also known as CNN1 or calponin-a is a 34-kilodalton protein that plays an important role in muscle contraction. Found mainly in smooth muscle tissues calponin 1 interacts with actin and myosin modulating their interactions and contributing to muscle contraction mechanics. It inhibits the ATPase activity of myosin which affects the contractile capacity of smooth muscle. These interactions are important for maintaining the proper function and tone of vascular and visceral smooth muscles.

Biological function summary

Calponin 1 acts as a regulatory protein in smooth muscle contraction by stabilizing actin filaments and modulating their interaction with other contractile proteins. It forms part of the thin filament-associated complex where it functions to control the conformational state of actin. This complex includes other proteins such as tropomyosin and troponin which together regulate the calcium-sensitive interactions between actin and myosin. The regulatory ability of calponin 1 contributes to the fine-tuning of smooth muscle contraction and relaxation processes.

Pathways

Calponin 1 plays a role in the RhoA/ROCK signaling pathway and the calcium-sensitive contractile pathway. These pathways are integral to smooth muscle contraction regulation and involve proteins such as Rho kinase (ROCK) and myosin light chain kinase (MLCK). Calponin 1 contributes to the modulation of the phosphorylation status of myosin light chains influencing the contractile response to various stimuli. This points to its involvement in the physiological response mechanism to vasoconstrictive agents.

Associated diseases and disorders

Calponin 1 is linked to cardiovascular diseases like hypertension and vascular disorders. Its regulatory functions in smooth muscle contraction can influence vascular tone and blood pressure connecting it to conditions like atherosclerosis. Moreover calponin 1 interacts with proteins such as filamin and α-actinin which are also implicated in muscle contraction-related disorders. Researchers investigate these interactions to understand their contributions to the pathogenesis of such diseases.

    ab197640 staining Calponin 1 in HeLa cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab197640 at 1/50 dilution (shown in red) and Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 100% methanol (5min).
