MGI Phenotype FUNCTION: The protein encoded by this gene is one of several similar proteins that bind insulin-like growth factors I and II (Igf-I and Igf-II). The encoded protein can be secreted into the bloodstream, where it binds Igf-I and Igf-II with high affinity, or it can remain intracellular, interacting with many different ligands. Two transcript variants, one encoding a secreted isoform and the other encoding a nonsecreted isoform, have been found for this gene. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygous mutation of this gene results in reduced spleen, heart and kidney size and increased liver weight. Homozygotes for another allele exhibit a normal phenotype. [provided by MGI curators]
