MGI Phenotype FUNCTION: This gene encodes a type I transmembrane protein. The encoded protein is an essential component of the cubulin receptor complex which is thought to play a role in coordinating growth and patterning of the embryo. This protein is thought to modulate a bone morphogenetic protein (BMP) signaling pathway. A homoygous mutation in the mouse gene results in the lack of an amnion in embryos. Mutations in the human gene are associated with Megaloblastic Anemia-1. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygous mutation of this gene results in embryonic growth arrest between the mid and late streak stages of gastrulation and abnormal ectoderm formation, followed by death. Generation of middle primitive streak derivatives is impaired, leading to absence of mesoderm and somites. [provided by MGI curators]
