Introduction

May modulate immune response and may play a role in inflammation (PubMed:36649229). Down-modulates STAT3 signaling throught direct interaction with IL6ST, resulting in the inhibition of phosphorylation of STAT3 at 'Tyr-705' (PubMed:26927669). May negatively regulates AKT signaling by modulating the activity of mTORC2 complex through RICTOR interaction (By similarity).

Cell-surface proteins (CSPs) mediate intercellular communication throughout the lives of multicellular organisms. However, there are no generalizable methods for quantitative CSP profiling in specific cell types in vertebrate tissues. Here, we present in situ cell-surface proteome extraction by extracellular labeling (iPEEL), a proximity labeling method in mice that enables spatiotemporally precise labeling of cell-surface proteomes in a cell-type-specific environment in native tissues for discovery proteomics. Applying iPEEL to developing and mature cerebellar Purkinje cells revealed differential enrichment in CSPs with post-translational protein processing and synaptic functions in the developing and mature cell-surface proteomes, respectively. A proteome-instructed in vivo loss-of-function screen identified a critical, multifaceted role for Armh4 in Purkinje cell dendrite morphogenesis. Armh4 overexpression also disrupts dendrite morphogenesis; this effect requires its conserved cytoplasmic domain and is augmented by disrupting its endocytosis. Our results highlight the utility of CSP profiling in native mammalian tissues for identifying regulators of cell-surface signaling.

Armadillo repeat and Armadillo-like helical domain containing proteins form a large family with diverse and fundamental functions in many eukaryotes. Herein we investigated the spatiotemporal expression pattern of Armadillo-like helical domain containing 4 (or Armh4) as an uncharacterized protein coding mouse gene, within the mouse embryo during the initial stages of heart morphogenesis. We found Armh4 is initially expressed in both first heart field as well as the second heart field progenitors and subsequently within predominantly their cardiomyocyte derivatives. Armh4 expression is initially cardiac-restricted in the developing embryo and is expressed in second heart field subpharyngeal mesoderm prior to cardiomyocyte differentiation, but Armh4 diminishes as the embryonic heart matures into the fetal heart. Armh4 is subsequently expressed in craniofacial structures and neural crest-derived dorsal root and trigeminal ganglia. Whereas lithium chloride-induced stimulation of Wnt/β-catenin signaling elevated Armh4 expression in both second heart field subpharyngeal mesodermal progenitors and outflow tract, right ventricle and atrial cardiomyocytes, neither a systemic loss of Islet-1 nor an absence of cardiac neural crest cells had any effect upon Armh4 expression. These results confirm that Wnt/β-catenin-responsive Armh4 is a useful specific biomarker of the FHF and SHF cardiomyocyte derivatives only.

Comparison of Migratory and Resident Populations of Brown Trout Reveals Candidate Genes for Migration Tendency

Candidate genes associated with migration have been identified in multiple taxa: including salmonids, many of whom perform migrations requiring a series of physiological changes associated with the freshwater-saltwater transition. We screened over 5,500 SNPs for signatures of selection related to migratory behavior of brown trout Salmo trutta by focusing on ten differentially migrating freshwater populations from two watersheds (the Koutajoki and the Oulujoki). We found eight outlier SNPs potentially associated with migratory versus resident life history using multiple (≥3) outlier detection approaches. Comparison of three migratory versus resident population pairs in the Koutajoki watershed revealed seven outlier SNPs, of which three mapped close to genes ZNF665-like, GRM4-like, and PCDH8-like that have been previously associated with migration and smoltification in salmonids. Two outlier SNPs mapped to genes involved in mucus secretion (ST3GAL1-like) and osmoregulation (C14orf37-like). The last two strongly supported outlier SNPs mapped to thermally induced genes (FNTA1-like, FAM134C-like). Within the Oulujoki, the only consistent outlier SNP mapped close to a gene (EZH2) that is associated with compensatory growth in fasted trout. Our results suggest that a relatively small yet common set of genes responsible for physiological functions associated with resident and migratory life histories is evolutionarily conserved.
