EnsemblReg Get Motif Features

Get transcription factor (TF) binding motif features in a genomic region from the Ensembl REST API. Returns motif instances with their binding matrix IDs, TF complex names, scores, and genomic positions. Use this to identify which transcription factors may bind to a specific genomic region, essential for understanding gene regulation, epigenomics, and cis-regulatory elements. Example: BRAF locus (chr7:140424943-140524564) returns 50 TF binding motif instances including PAX5, NR2F1, CEBPA.
