betacoronavirus non-structural protein 2 (Nsp2) similar to SARS-CoV Nsp2, and related proteins from betacoronaviruses in the B lineage; Non-structural proteins (Nsps) from Severe acute respiratory syndrome coronavirus (SARS-CoV) and betacoronaviruses in the sarbecovirus subgenus (B lineage) are encoded in ORF1a and ORF1b. Post infection, the SARS-CoV genomic RNA is released into the cytoplasm of the cell and translated into two long polyproteins (pp), pp1a and pp1ab, which are then autoproteolytically cleaved by two viral proteases Nsp3 and Nsp5 into smaller subunits. Nsp2 is one of these subunits. The function of Nsp2 remains unknown. Deletion of Nsp2 from the SARS-CoV genome results in only a modest reduction in viral titers. Rather than playing a role in viral replication, SARS-CoV Nsp2 may be involved in altering the host cell environment; it has been shown to interact with two host proteins, prohibitin 1 (PHB1) and PHB2 which have been implicated in cellular functions, including cell-cycle progression, cell migration, cellular differentiation, apoptosis, and mitochondrial biogenesis.

Nsp2 is one of these subunits. This alpha- and betacoronavirus family includes alphacoronavirus human coronavirus 229E (HCoV-229E) Nsp2, betacoronavirus Severe acute respiratory syndrome coronavirus (SARS-CoV) Nsp2, SARS-CoV-2 Nsp2, and Murine hepatitis virus (MHV) Nsp2 (also known as p65).

MHV Nsp2/p65, different from SARS-CoV Nsp2, may play an important role in the viral life cycle. This family may be distantly related to the gammacoronavirus Avian infectious bronchitis virus (IBV) Nsp2; IBV Nsp2 is a weak protein kinase R (PKR) antagonist, which may suggest that it plays a role in interfering with intracellular immunity.

The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits

(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
