Figure 11From: Phosphorylation of HIV-1 Tat by CDK2 in HIV-1 transcriptionSerine residues at position 16 and 46 are highly conserved in Tat isolates. The 158 sequences of Tat isolates deposited to PubMed database were analyzed for the presence of serines at position 16, 23, 46, 61, 68, 70, 73, 74 and 75. Presence of a serine at the indicated position is presented as a percent of the total number of the isolates analyzed.Back to article page
