Background: H3L

Monkeypox Virus (MPXV), the virus that causes monkeypox infection in both humans and animals, is a double-stranded DNA virus that has had a recent global outbreak in 2022 (1). MPXV belongs to the Poxviridae family of viruses (2). It consists of several key subunits including a surface membrane fusion protein (A29L, ~14 kDa), two separate envelope proteins (A30L ~14 kDa and H3L ~32kDa), an envelope glycoprotein, A35R ~15 kDa), a receptor glycoprotein that mimics IFN-alpha/beta (B16, ~37 kDa), a palmitoylated EEV membrane glycoprotein (C19L, ~35 kDa), a secreted IL-18 binding protein (D6L, ~14 kDa), a cell surface-binding protein (E8L, ~32 kDa), a telomere binding protein (I1L, ~36kDa), and a subunit required for DNA packaging (L1R, 18 kDa) (2, 3). The H3L subunit is an envelope protein that assists in virion attachment (4). It belongs to the chordopoxvirinae protein H3 family and is 278 ammino acids long (2). H3L has been looked at for use in testing kits and immunoassays due to its high abundance in MPXV patients after viral infection (5). Other studies have shown that the H3L subunit plays a role in the Vaccinia virus based vaccine's ability to cross vaccinate from MPXV (6).
