xtr-1 encodes a protein with similarity to TRA-2A and TRA-2B in a region known as the MX region, hypothesized to be a protein-protein interaction domain involved in negatively regulating tra-2 activity in the germ line.
Predicted to enable transmembrane signaling receptor activity. Predicted to be involved in germ-line sex determination. Predicted to be located in plasma membrane.
Following advice from [Hodgkin J], the trx gene class was renamed to xtr. Hence this gene used to be called trx-1. [krb 020614]
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.
