CC -!- FUNCTION: IGF-binding proteins prolong the half-life of the IGFs and
CC have been shown to either inhibit or stimulate the growth promoting
CC effects of the IGFs on cell culture. They alter the interaction of IGFs
CC with their cell surface receptors. {ECO:0000256|ARBA:ARBA00003811}.
CC -!- SUBUNIT: Binds IGF2 more than IGF1. {ECO:0000256|ARBA:ARBA00011592}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|ARBA:ARBA00004613}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU00500}.
