5'-AMP-activated protein kinase catalytic subunit alpha-2


Locus: CELE_T01C8.1


Wormbase description: aak-2 encodes one of two C. elegans homologs of the catalytic alpha subunit of AMP-activated protein kinases (AMPKs); in C. elegans, aak-2 functions downstream of environmental stressors, energy level signals (AMP:ATP ratio), and daf-2-mediated insulin signaling to positively regulate adult lifespan; in regulating lifespan, aak-2 likely acts in parallel with daf-16/FOXO; aak-2 activity is also required for dauer formation in daf-2 mutant animals at high temperature in a manner independent of the AMP:ATP ratio; in the germline, aak-2 functions downstream of daf-2 and daf-7, and in parallel to par-4 and aak-1, to negatively regulate germline proliferation during dauer development; in vitro, AAK-2 exhibits AMP-enhanced kinase activity against a known AMPK substrate, the SAMS peptide.

Spectrin beta chain


Locus: CELE_K11C4.3


Wormbase description: unc-70 encodes two isoforms of a beta-spectrin ortholog required for normal body curvature and shape, normal movement, and correct localization of the alpha-spectrin SPC-1; the predominant UNC-70 isoform is expressed in all embryonic cells except the intestine, at the plasma membrane at sites of intercellular contact; UNC-70 becomes largely restricted to muscles and neurons from hatching to adulthood, with expression in adult spermetheca and hypodermis as well; conversely, the minor isoform is predominantly expressed in gut, and is also apposed to intercellular membrane junctions in embryos; sma-1 mutations (which impair the one beta-H-spectrin ortholog in C. elegans) enhance the unc-70 phenotype; UNC-70 is dispensable for viability (under undemanding laboratory culture conditions).
