MGI Phenotype FUNCTION: Many different endogenous retrovirus families are expressed in normal placental tissue at high levels, suggesting that endogenous retroviruses are functionally important in reproduction. This gene is part of a mouse endogenous retrovirus provirus on chromosome 5 that has inactivating mutations in the gag and pol genes. This gene is the envelope glycoprotein gene which appears to have been selectively preserved. The gene's protein product plays a major role in placental development and trophoblast fusion. The protein has the characteristics of a typical retroviral envelope protein, including a cleavage site that separates the surface (SU) and transmembrane (TM) proteins which form a heterodimer.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit lethality between E11.5 and E14.5 associated with defective placental layrinth formation, impaired placental transport, and increased trophoblast cells. [provided by MGI curators]
