CK1 and PP1 regulate Rift Valley fever virus genome replication through L protein phosphorylation.

Rift Valley fever virus (RVFV) is an arbovirus in the Phenuiviridae family identified initially by the large 'abortion storms' observed among ruminants; RVFV can also infect humans. In humans, there is a wide variation of clinical symptoms ranging from subclinical to mild febrile illness to hepatitis, retinitis, delayed-onset encephalitis, or even hemorrhagic fever. The RVFV is a tri-segmented negative-sense RNA virus consisting of S, M, and L segments.

An LIR motif in the Rift Valley fever virus NSs protein is critical for the interaction with LC3 family members and inhibition of autophagy.

Rift Valley fever virus (RVFV) is a viral zoonosis that causes severe disease in ruminants and humans. The nonstructural small (NSs) protein is the primary virulence factor of RVFV that suppresses the host's antiviral innate immune response. Bioinformatic analysis and AlphaFold structural modeling identified four putative LC3-interacting regions (LIR) motifs (NSs 1-4) in the RVFV NSs protein, which suggest that NSs interacts with the host LC3-family proteins.

An academic-community partnership to improve care for the underserved.

Despite the need for a robust primary care workforce, the number of students and residents choosing general internal medicine careers continues to decline. In this article, the authors describe their efforts at the University of California, Davis School of Medicine to bolster interest in internal medicine careers and improve the quality of care for medically underserved populations through a tailored third-year residency track developed in partnership with the Sacramento County Department of Health and Human Services. The Transforming Education and Community Health (TEACH) Program improves continuity of care between inpatient and outpatient settings, creates a new multidisciplinary teaching clinic in the Sacramento County health system, and prepares residents to provide coordinated care for vulnerable populations.

Phosphorylation of the postsynaptic density-95 (PSD-95)/discs large/zona occludens-1 binding site of stargazin regulates binding to PSD-95 and synaptic targeting of AMPA receptors.

Dynamic regulation of AMPA-type receptors at the synapse is proposed to play a critical role in alterations of the synaptic strength seen in cellular models of learning and memory such as long-term potentiation in the hippocampus. Stargazin, previously identified as an AMPA receptor (AMPAR)-interacting protein, is critical for surface expression and synaptic targeting of AMPARs. Stargazin interacts with postsynaptic density-95/discs large/zona occludens-1 (PDZ) proteins via a C-terminal PDZ binding motif.
