Abstract: Identification of genes regulated by the same transcription factor (TF) is a major problem in analysis of regulation. The key step in detection of a group of co-regulated genes (regulon) is prediction of TF binding sites (TFBS). This is what positional weight matrix (PWM) is for. This matrix is applied to upstream region of a gene, and high-scoring sites are considered as putative TFBSs. Choice of threshold for the scoring function is a separate complicated problem. Usually, the threshold is chosen manually. Some methods for automated threshold detection exist, but they are based on selection of threshold for different functions. In this paper, we present an approach for regulon prediction based on a probabilistic method of threshold detection. The optimal probability computed by this method can be used to estimate the quality of the PWM itself. It can be useful when the matrix is a result of regulatory motif prediction program.
