SIDT2 (SID1 Transmembrane Family Member 2): SIDT2 is a gene that encodes a protein involved in the cellular uptake of RNA molecules, playing a role in RNA interference (RNAi) mechanisms. It is important in the study of gene regulation and has potential implications for RNA-based therapeutics. SIDT2’s function in RNA transport is crucial for understanding how cells regulate gene expression and respond to external RNA molecules.
