1. Vpu and bicistronic mRNA in a Rev-dependent manner, presumably by leaky scanning of ribosomes through the vpu initiation codon.
2. This protein is transcribed from a monocistronic mRNA as well as a bicistronic mRNA, which also encodes growth differentiation factor 1.
3. Virus protein " u " ( Vpu ) is an oligomeric, 81-amino acid type I membrane protein ( 16 kDa ) that is translated from vpu-env bicistronic mRNA . The N-terminus of Vpu encoding the transmembrane ( TM ) anchor represents an active domain important for the regulation of virus release but not CD4 degradation . The C-terminal cytoplasmic domain ( 54 residues ) that contains a pair of serine residues ( at positions 52 and 56 ) constitutively phosphorylated by casein kinase II . The phosphorylation of two serine residues in the cytoplasmic domain is critical for CD4 degradation in the ER . Based on 2D 1H NMR spectroscopy of a peptide corresponding to the cytoplasmic domain of Vpu, it was proposed that the cytoplasmic domain of Vpu contains two ?-helical domains, helix-1 and helix-2, which are connected by an unstructured region containing the two conserved phosphoseryl residues.
