Beta-catenin/armadillo-related protein 1

bar-1

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Participates in the Wnt signaling pathway which affects cell fate and may regulate the stem cell divisions of seam cells during larval development. Functions as a transcriptional activator but is dependent on the interaction with pop-1. Involved in maintaining lin-39 Hox expression and regulating glr-1 abundance at the synapses. Required for mab-5 expression during Q neuroblast migration and for oxidative stress-induced daf-16 signaling. Has roles in egg laying, vulva precursor cell fate determination, Q neuroblast migration, posterior ectodermal cell P12 specification, movement, body length, male tail development and dauer induction. Functionally redundant to wrm-1 and hmp-2.8 Publications

Miscellaneous

Worms lacking bar-1 exhibit abnormalities in vulval development due to incorrect cell fate specification, resulting in the following phenotypes, multivulva (Muv), protruding vulva (Pvl) and egg laying defective (Egl). Mutants also show defects in Q neuroblast migration, uncoordinated movement (Unc) and reduced superoxidase dismutase levels. Null mutants can be rescued by wrm-1 and hmp-2 when expressed from the bar-1 promoter. Double mutants also lacking dpy-22 show reduced body length, male tail morphology abnormalities (Mab) and dauer induction.5 Publications
