Substrate-recognition component of some (SKP1-CUL1-F-box protein)-type E3 ubiquitin-protein ligase complexes. The SCF(FBXL14) complex acts by mediating ubiquitination and subsequent degradation of SNAI1 (By similarity). Part of a SCF (SKP1-cullin-F-box) ubiquitin-protein ligase complex. Interacts with SKP1 and CUL1. Interacts with SNAI1; the interaction requires the phosphorylation of the two serine residues in the substrate destruction motif D-S-G-X(2,3,4)-S (By similarity).
