>cd02413 40S_S3_KH K homology RNA-binding (KH) domain of the eukaryotic 40S small ribosomal subunit protein S3. S3 is part of the head region of the 40S ribosomal subunit and is believed to interact with mRNA as it threads its way from the latch into the channel. The KH motif is a beta-alpha-alpha-beta-beta unit that folds into an alpha-beta structure with a three stranded beta-sheet interupted by two contiguous helices. In general, KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA.
