Description (originally from EcoCyc[1]) IS2 insertion element repressor InsA

Comments (originally from EcoCyc[1]) InsA is a transcriptional repressor for the insertion element IS2.

InsA binds in the left inverted repeat of IS2, upstream from the insA promoter in IS2. InsA represses IS2 gene transcription [2][3][4][5][6][7][8][9][10][11].

This protein object represents the product of multiple, distinct genes that encode proteins of identical amino acid sequence.
