DRAMP02473

Comments Information
Function
- Adopts an amphipathic alpha helical conformation, that may allow to partition into the target membrane. No hemolytic and cytotoxic activities have been observed on mammalian cells.
Tissue specificity
- Expressed by the venom gland, stomach, trachea, skin, muscle, heart, kidney, lung, brain, intestine, spleen, liver, and ovary.
Miscellaneous
- A predicted cleavage site is located at position Val-157-158-Lys, giving a peptide of 34 residues instead of the 30 residues found for the purified protein. The 30 residues cathelicidin-BF could result from a further processing.
