cdh-4 encodes a Fat-like cadherin homolog; CDH-4 is required for axon fasciculation, cell migration, and hypodermis and pharyngeal development; in addition, CDH-4 functions together with the FMI-1 flamingo-like cadherin to regulate development of the GABAergic VD motorneurons; cdh-4 is widely expressed beginning early in development, but by the L3 larval stage expression is confined to the VD GABAergic motorneurons.
Predicted to enable calcium ion binding activity. Predicted to be involved in homophilic cell adhesion via plasma membrane adhesion molecules. Predicted to be located in membrane. Expressed in several structures, including QL; QR; VD neuron; non-striated muscle; and rectal gland cell. Human ortholog(s) of this gene implicated in carcinoma (multiple); colorectal cancer; and spinocerebellar ataxia 45. Is an ortholog of human FAT1 (FAT atypical cadherin 1); FAT2 (FAT atypical cadherin 2); and FAT3 (FAT atypical cadherin 3).
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.
