Functional Role Of Myosin-Binding Protein H In Thick Filaments Of Developing Vertebrate Fast-Twitch Skeletal Muscle, Andrew F Mead, Marilyn J Cipolla, Aaron N Johnson, Christina A Gurnett, Et Al.

2020-Current year OA Pubs

Myosin-binding protein H (MyBP-H) is a component of the vertebrate skeletal muscle sarcomere with sequence and domain homology to myosin-binding protein C (MyBP-C). Whereas skeletal muscle isoforms of MyBP-C (fMyBP-C, sMyBP-C) modulate muscle contractility via interactions with actin thin filaments and myosin motors within the muscle sarcomere "C-zone," MyBP-H has no known function. This is in part due to MyBP-H having limited expression in adult fast-twitch muscle and no known involvement in muscle disease. Quantitative proteomics reported here reveal that MyBP-H is highly expressed in prenatal rat fast-twitch muscles and larval zebrafish, suggesting a conserved role in muscle development and …

Addressing Agency In Intersectional Leadership: The Consequences Of Agentic Leader Behaviors For Black And White Men And Women In Leadership, Sydney Roux

LSU Master's Theses

As Black women gain representation in business and entrepreneurial leadership, it is important to consider how these women will be perceived as leaders. Role congruity theory (RCT) posits that women’s gender roles do not align with the leadership role which often negatively impacts leader evaluations. However, RCT is often employed without a racial context where women are presumed to be White, and thus, it is unclear if the same assumptions can be applied to Black women. Leadership scholars have identified the ways in which attributions and expectations of leaders are shaped by both demographic characteristics and behavioral events. Because Black …
