Hairy/enhancer-of-split related with YRPW motif-like protein (HEYL)

Downstream effector of Notch signaling that might be required for cardiovascular development (By similarity). Transcriptional repressor which binds preferentially to the canonical E box sequence 5'-CACGTG-3' (By similarity).

Represses transcription by the cardiac transcriptional activators GATA4 and GATA6. .
