Target Background | Defensin are 3-4 kDa antimicrobial peptides of which three distinct families have been identified; α-defensin, β-defensins, and insect defensins. Rat β-Defensin 1, as a member of the β-defensin family, is a salt-sensitive antimicrobial peptide present in epithelia of the lung and urogenital tract. The predicted amino acid sequence shows the hallmark features of other known epithelial β-defensins, including the ordered array of six cysteine residues. |
Name | Defb1 |
---|---|
Function | Has bactericidal activity. May act as a ligand for C-C chemokine receptor CCR6. Positively regulates the sperm motility and bactericidal activity in a CCR6-dependent manner. Binds to CCR6 and triggers Ca2+ mobilization in the sperm which is important for its motility. |
Cellular Location | Secreted {ECO:0000250|UniProtKB:P60022}. Membrane {ECO:0000250|UniProtKB:P60022}. Note=Associates with tumor cell membrane-derived microvesicles. {ECO:0000250|UniProtKB:P60022} |
Tissue Location | Highly expressed in kidney. |
