Question

The protein structural motif domain- helix loop helix are contained by all of the following except ________

(a) Scleraxis

(b) Neurogenins

(c) Transcription Factor 4

(d) Leucine zipper

The question was asked by my school teacher while I was bunking the class.

This interesting question is from Protein Motifs and Domain Prediction topic in division Sequence Alignment of Bioinformatics

Answer 1

The correct answer is (d) Leucine zipper

To explain I would say: Leucine zipper is associated with gene regulation and contains alpha helix with leucine at every 7th amino acid. While rest of them are under one of the largest families of dimerizing transcription factors.
