Talk about confusing:

This entry: https://en.wikipedia.org/wiki/ER-X and this entry: https://en.wikipedia.org/wiki/ERx

should be deleted or collapsed into ESRA (https://en.wikipedia.org/wiki/Estrogen_receptor_alpha or https://en.wikipedia.org/wiki/Membrane_estrogen_receptor).

ER-X and ERx are apparently membrane-targeted isoforms of the estrogen alpha receptor (ERSA) gene and protein. The original publication on ER-X by Toran-Allerand (2002) argued that this was a new receptor gene, rather than a splice variant of ERSA, and promised to provide protein sequence in support, but 17 years later, there still is no support for a distinct ER-X gene in any genome database for mouse or human.
