Sequence motif, a sequence pattern of nucleotides in a DNA sequence or amino acids in a protein
Structural motif, a pattern in a protein structure formed by the spatial arrangement of amino acids
Short linear motif, a stretch of protein sequence that mediates protein–protein interaction

chip-seq motif discovery:
通过motif预测DNA上可能会有哪些转录因子结合。每个转录因子都有一个DNA结合结构域（DBD），喜欢结合在特定DNA序列上，也就是motif。如果我感兴趣的基因上游DNA有某个TF的motif，那么该TF就有可能结合这段DNA，从而调控下游基因表达。
