CC -!- FUNCTION: Hormone involved in the regulation of erythrocyte
CC proliferation and differentiation and the maintenance of a
CC physiological level of circulating erythrocyte mass. Binds to EPOR
CC leading to EPOR dimerization and JAK2 activation thereby activating
CC specific downstream effectors, including STAT1 and STAT3.
CC {ECO:0000250|UniProtKB:P01588}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Produced by kidney or liver of adult mammals and by
CC liver of fetal or neonatal mammals.
CC -!- SIMILARITY: Belongs to the EPO/TPO family. {ECO:0000305}.
