Ankyrins are a ubiquitously expressed family of intracellular adaptor proteins involved in targeting diverse proteins to specialized membrane domains in both the plasma membrane and the endoplasmic reticulum(Bennett and Baines, 2001). Vertebrate ankyrin polypeptides fall into three classes, each containing multiple alternatively spliced variants: ankyrins-R (R for restricted distribution, and the prototypic ankyrin first characterized in erythrocytes;also expressed in a subset of neurons and striated muscle) encoded by Ank1 on human chromosome 8p11; ankyrins-B (B for broadly expressed;first characterized in brain, but now recognized in most cell types) encoded by Ank2 on human chromosome 4q25-27; and ankyrins-G (G for giant size and general expression, first characterized as a 480 kDa polypeptide in the nervous system; expressed in most cell types) encoded by Ank3, on human chromosome 10q21. Although ankyrin genes are not present in the completed genomes of yeast or plants, simple metazoans including Drosophila melanogaster (...

Origin and evolution of mitochondrial inner membrane composition

In this Review, Kailash Venkatraman and colleagues provide an examination of the morphological similarities between prokaryotic intracytoplasmic membranes and mitochondrial inner membranes, and whether cristae evolution has driven specialisation of the mitochondrial lipidome.
Resolution in super-resolution microscopy
Super-resolution microscopy (SRM) has emerged as a powerful tool for biological discovery. In this Perspective, Kirti Prakash and colleagues compile expert opinions on crucial, yet often overlooked, aspects of SRM that are essential for maximising its benefits and advancing the field.
