sph-1 encodes a member of the synaptophysin/synaptoporin family that contains a MARVEL domain, a membrane-associating domain found in lipid-associating proteins, and contains a transmembrane domain.
Located in cytoplasmic vesicle. Expressed in anal sphincter muscle and pharyngeal muscle cell. Human ortholog(s) of this gene implicated in Alzheimer's disease and non-syndromic X-linked intellectual disability 96. Is an ortholog of human SYNPR (synaptoporin) and SYPL1 (synaptophysin like 1).
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.
