A trans membrane P4H (P4H-TM) is a recently identified member of the family. Biallelic loss of function P4H-TM mutations cause a severe autosomal recessive intellectual disability syndrome in humans, but functions of P4H-TM are essentially unknown at cellular level. Our microarray data on P4h-tm(-/-) mouse cortexes where P4H-TM is abundantly expressed indicated expression changes in genes involve...
