ACTN2 [ENSP00000355537]
 
actinin, alpha 2; F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein
KCNA4 [ENSP00000328511]
 
potassium voltage-gated channel, shaker-related subfamily, member 4; Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient
