This entry includes SDA1 protein and its homologues. SDA1 is a Saccharomyces cerevisiae protein which is involved in the control of the actin cytoskeleton. The protein is essential for cell viability and is localised in the nucleus [1]. This region is found after the HEAT repeats found at SDA1 N-terminal (Pfam:PF08158). According to structure predictions, it consists of short alpha helices and disorder region.
