C2CD4B (C2 Calcium-Dependent Domain Containing 4B): C2CD4B is a gene that encodes a protein containing C2 calcium-dependent domains. These domains are typically found in proteins involved in calcium-mediated cellular processes. While the exact function of C2CD4B is still being studied, its structure suggests it may play a role in calcium signaling pathways and membrane dynamics. Additional research is necessary to determine its specific function in cellular activities.
