| Abstrakt: | The placental leucine aminopeptidase/insulin-regulated aminopeptidase, endoplasmic reticulum aminopeptidase 1 and endoplasmic reticulum aminopeptidase 2 are part of a distinct subfamily of M1 aminopeptidases termed the 'oxytocinase subfamily'. The subfamily members show molecular diversity due to differential usage of translation initiation sites, alternative splicing and multiple single nucleotide polymorphisms. It is becoming evident that, depending on their intracellular or extracellular location, members of the oxytocinase subfamily play important roles in the maintenance of homeostasis, including the regulation of blood pressure, maintenance of normal pregnancy, retention of memory and trimming of antigenic peptides presented to major histocompatibility complex class I molecules, by acting as either aminopeptidases or binding partners of specific functional proteins in the cells. Based on their molecular diversity and moonlighting protein-like properties, it is conceivable that the subfamily members exert pleiotropic effects during evolution, to become important players in the regulation of homeostasis.
