C2CD4B (C2 Calcium-Dependent Domain Containing 4B): C2CD4B is a gene that encodes a protein featuring C2 calcium-dependent domains. These domains are commonly found in proteins that participate in calcium-mediated cellular processes. Although the exact function of C2CD4B remains under investigation, its structure suggests a potential role in calcium signaling pathways and membrane dynamics. Further research is needed to clarify its specific function in cellular activities.
