VISTA-induced tumor suppression by a four amino acid intracellular motif.

VISTA is a key immune checkpoint receptor under investigation for cancer immunotherapy; however, its signaling mechanisms remain unclear. Here we identify a conserved four amino acid (NPGF) intracellular motif in VISTA that suppresses cell proliferation by constraining cell-intrinsic growth receptor signaling. The NPGF motif binds to the adapter protein NUMB and recruits Rab11 endosomal recycling machinery.

Disparities in Surgical Intervention in Pediatric Patients With Submucous Cleft Palate and Velopharyngeal Dysfunction.

Objective: To evaluate factors impacting access to and timing of surgery in patients with submucous cleft palate (SMCP) and velopharyngeal dysfunction (VPD).

Study Design: Retrospective cohort study.

Setting: Single academic medical center.

Towards assembling functional cyanobacterial β-carboxysomes in Oryza sativa chloroplasts.

The major limiting factor of photosynthesis in C3 plants is the enzyme, rubisco which inadequately distinguishes between carbon dioxide and oxygen. To overcome catalytic deficiencies of Rubisco, cyanobacteria utilize advanced protein microcompartments, called the carboxysomes which envelopes the enzymes, Rubisco and Carbonic Anhydrase (CA). These microcompartments facilitate the diffusion of bicarbonate ions which are converted to CO by CA, following in an increase in carbon flux near Rubisco boosting CO fixation process.

Structural analysis of genetic variants of the human tumor suppressor Palb2 coiled-coil domain.

The tumor suppressor PALB2 is a key player in the Homologous Recombination (HR) pathway, functionally connecting BRCA proteins at the DNA damage site. PALB2 forms homodimers via its coiled-coil domain, and during HR, it forms a heterodimeric complex with BRCA1 using the same domain. However, the structural details of the human PALB2 coiled-coil domain are unknown.
