Substrate-recognition component of some SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin-protein ligase complexes. The SCF(FBXL14) complex acts by mediating ubiquitination and subsequent degradation of SNAI1. . This is the function of FBXL14 (F-box and leucine rich repeat protein 14, ENSG00000171823).
