Table 1 HIV and influenza viral proteins. Some of the most important HIV and influenza viral proteins are listed with a brief description of their functions. They are listed by the order of their location in the corresponding virions [710].

From: Protein intrinsic disorder toolbox for comparative analysis of viral proteins

Major HIV proteins
Protein Function of the Protein Location
SU(gp120) Binding of host's CD4 to itself Virion Surface(SU)
TM (gp41) Involved in fusion with host Transmembrane (TM) at the Virion Envelope
MA (p17) Matrix Beneath the Enevelope
Vpua Virion release  
Vpr Nucleus transportation of viral proteins Within capsid and beneath matrix
CA (p24) Main core protein Nucleocapsid
PR (p11) Protease. Within the Core
RT (p66) Reverse Transcriptase Within th Core
IN (p32) Integrase. Within the Core
Tata Transcription factor NAa
Major influenza A virus proteins
Protein Function/Description Location
HA Hemagglutinin allows the attachhment of host's CD4 to itself Envelope
NA Neuraminidase cleaves sialic acud group to allow virion release into the extracellular region. Transmembrane (TM) at the Virion Envelope
MA (M1, M2) Protein assembly with membrane binding and disassociation Matrix: Beneath the Enevelope
NS1 Non-Structural Protein. Inhibits RNA splicing. RNA binding Within capsid and beneath matrix
NS2 Transportation of RNPb to cytoplasm  
NP Nucleoprotein Nucleocapsid
PB1 Main core protein Binds to Nucleocapsid
  1. a Positions of VPU and Tat in the virion is unclear
  2. b Ribonucleoprotein (RNP)
