JASPAR: Motif Matrix
jaspar_motifRead-onlyIdempotent
Fetch a JASPAR transcription factor binding profile by matrix ID, returning the raw position-frequency matrix, TF class, assay type, species, and references.
Instructions
Fetch one JASPAR binding profile by matrix id, including its raw position-frequency matrix (PFM: per-base count vectors keyed A/C/G/T) plus TF class/family, assay type, source species, UniProt accessions, PubMed refs, IUPAC consensus, and the sequence-logo URL. The drill-down companion to tf_binding_motifs, which returns the derived consensus but not the matrix. Accepts a versioned id (MA0570.1) or a bare base id (MA0570, which resolves to the newest version). Unknown ids raise a typed NotFoundError.
