ACS OMEGA 2020; 5:25841-25847. [PMID: 33073109 PMCID: PMC7557935 DOI: 10.1021/acsomega.0c03171] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 09/23/2020] [Indexed: 06/11/2023]
Abstract
G0S2 is a small protein of 103 residues in length that is involved in multiple cellular processes. To date, several reports have shown that G0S2 functions by making direct protein-protein interactions with key proteins. In lipolysis, G0S2 specifically interacts with adipose triglyceride lipase, inhibiting its activity and resulting in lipolysis being downregulated. In a similar way, G0S2 also participates in the regulation of apoptosis, cell proliferation, and oxidative phosphorylation; however, information regarding G0S2 structural and biophysical properties is limited. In this work, we conducted a comparative structural analysis of human and mouse G0S2 proteins. Bioinformatics suggests the presence of a disordered C-terminal region in human G0S2. Experimental characterization by size-exclusion chromatography and dynamic light scattering showed that human and mouse G0S2 have different hydrodynamic properties. In comparison to the mouse G0S2, which behaves similar to a globular protein, the human G0S2 shows an elongated conformation, most likely by displaying a disordered C-terminal region. Further analysis of hydrodynamic properties under denaturing conditions suggests the presence of a structural element in the mouse protein that undergoes an order to disorder transition at low urea concentration. Structural analysis by circular dichroism revealed that in native conditions, both proteins are mainly unstructured, showing the presence of beta sheet structures. Further analysis of CD data suggests that both proteins belong to the premolten globule family of intrinsically disordered proteins. We suggest that the intrinsic disorder observed in the G0S2 protein may facilitate its interaction with multiple partners in the regulation of cellular metabolism.

Abstract
This is the 6th issue of the Digested Disorder series that continues to use only 2 criteria for inclusion of a paper to this digest: The publication date (a paper should be published within the covered time frame) and the topic (a paper should be dedicated to any aspect of protein intrinsic disorder). The current digest issue covers papers published during the second quarter of 2014; i.e., during the period of April, May, and June of 2014. Similar to previous issues, the papers are grouped hierarchically by topics they cover, and for each of the included papers a short description is given on its major findings.

Abstract
This article continues an "Unreported Intrinsic Disorder in Proteins" series, the goal of which is to expose some interesting cases of missed (or overlooked, or ignored) disorder in proteins. The need for this series is justified by the observation that despite the fact that protein intrinsic disorder is widely accepted by the scientific community, there are still numerous instances when appreciation of this phenomenon is absent. This results in the avalanche of research papers which are talking about intrinsically disordered proteins (or hybrid proteins with ordered and disordered regions) not recognizing that they are talking about such proteins. Articles in the "Unreported Intrinsic Disorder in Proteins" series provide a fast fix for some of the recent noticeable disorder overlooks.

Abstract
This review opens a new series entitled “Unreported intrinsic disorder in proteins.” The goal of this series is to bring attention of researchers to an interesting phenomenon of missed (or overlooked, or ignored, or unreported) disorder. This series serves as a companion to “Digested Disorder” which provides a quarterly review of papers on intrinsically disordered proteins (IDPs) found by standard literature searches. The need for this alternative series results from the observation that there are numerous publications that describe IDPs (or hybrid proteins with ordered and disordered regions) yet fail to recognize many of the key discoveries and publications in the IDP field. By ignoring the body of work on IDPs, such publications often fail to relate their findings to prior discoveries or fail to explore the obvious implications of their work. Thus, the goal of this series is not only to review these very interesting and important papers, but also to point out how each paper relates to the IDP field and show how common tools in the IDP field can readily take the findings in new directions or provide a broader context for the reported findings.

The only 2 criteria for inclusion in this digest are the publication date (a paper should be published within the covered time frame) and topic (a paper should be dedicated to any aspect of protein intrinsic disorder). The current digest issue covers papers published during the third quarter of 2013; i.e., during the period of June, July, and September of 2013.

The current literature on intrinsically disordered proteins is overwhelming. To keep interested readers up to speed with this literature, we continue a "Digested Disorder" project and represent a series of reader's digest type articles objectively representing the research papers and reviews on intrinsically disordered proteins. The only 2 criteria for inclusion in this digest are the publication date (a paper should be published within the covered time frame) and topic (a paper should be dedicated to any aspect of protein intrinsic disorder). The current digest issue covers papers published during the period of April, May, and June of 2013.
