EnsemblReg Get Binding Matrix

Get a transcription factor binding matrix (position weight matrix/PWM) by stable ID from the Ensembl REST API. Returns the nucleotide frequency matrix, threshold, associated TF complexes, and consensus sequence. Binding matrices describe the DNA sequence preferences of transcription factors and are essential for predicting TF binding sites and understanding gene regulation. Example: ENSPFM0320 returns the PAX5 binding matrix with 18 positions.
