May act as a translational repressor which regulates translation of specific mRNAs by forming a complex with PUM2 that associates with the 3'-UTR of mRNA targets. Capable of interfering with the proadhesive and anti-invasive functions of E-cadherin. Up-regulates the production of MMP14 to promote tumor cell invasion. . This is the function of Ensembl gene identifier ENSG00000188613 (NANOS1, nanos C2HC-type zinc finger 1).
