Chromosome | 5 | NCBI Gene Number | 22022 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 7.0.0) Enables protein-tyrosine sulfotransferase activity. Acts upstream of or within fusion of sperm to egg plasma membrane involved in single fertilization and prevention of polyspermy. Predicted to be located in endoplasmic reticulum. Predicted to be active in Golgi apparatus. Orthologous to human TPST2 (tyrosylprotein sulfotransferase 2). PHENOTYPE: Spontaneous mutants show a delayed rise and a prolonged deficit of pituitary growth hormone resulting in delayed pubertal growth, hypothyroidism, and an enlarged adenohypophysis with aberrant chromophobic cells. Homozygous null mice show a modest but transient pubertal growth lag and male sterility. [provided by MGI curators] |
