1.A.80 The NS4a Viroporin (NS4a) Family

The NS4a peptide (54 aas; 1 TMS) has been shown to form pores (Madan et al., 2007). This protein is related to and represents a peptide fragment of the large glycoproteins of the Hepatitis C Virus P7 Viroporin Cation-selective Channel (HCV-P7) Family (TC# 1.A.53).

This family belongs to the .
