Thioredoxin domain-containing protein 3 (TXNDC3), also known as spermatid-specific thioredoxin-2 (Sptrx-2), is a protein that in humans is encoded by the NME8gene (also known as the TXNDC3 gene) on chromosome 7.[5][6]
This gene encodes a protein with an N-terminalthioredoxin domain and three C-terminal nucleoside diphosphate kinase (NDK) domains, but the NDK domains are thought to be catalytically inactive. The sea urchin ortholog of this gene encodes a component of sperm outer dynein arms, and the protein is implicated in ciliary function.[5]
