feh-1 encodes the single C. elegans member of the Fe65 protein family that affects embryonic and larval viability and pharyngeal pumping; the PTB2 domain binds to cytosolic domain of C. elegans APL-1 in vitro; expressed in the neuromuscular structures of the pharynx and in a subset of neurons.
Enables amyloid-beta binding activity. Involved in embryo development; feeding behavior; and nematode larval development. Located in actin filament. Expressed in nerve ring; pharynx; tail neurons; and ventral cord neurons. Human ortholog(s) of this gene implicated in Alzheimer's disease and cognitive disorder. Is an ortholog of human APBB2 (amyloid beta precursor protein binding family B member 2).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
