The MYO1F interactome reveals ASAP1, CD2AP and SH3KBP1 as novel adaptor proteins in podosomes and phagosomes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
MYO1F, a long-tailed myosin of class I, is selectively expressed in immune cells and upregulated in microglia associated with neurodegenerative pathogenesis. Myosin motor functions are regulated by adaptor proteins that mediate cargo attachment and motor recruitment. To define the MYO1F interactome, we used in situ proximity labelling and proteomics in human myeloid cells. We identified a distinct SH3-domain-dependent adaptor module comprising CD2AP, ASAP1, SH3BP2 and SH3KBP1 (herein termed the CASS group of proteins). Interestingly, CD2AP is an Alzheimer's disease (AD) risk gene upregulated in the microglia of individuals with AD, which are implicated in phagocytic responses to amyloid-β. Structural modelling and mutagenesis confirmed multivalent proline-rich motif interactions between the CASS group of proteins and the MYO1F SH3 domain. Additional binding partners associate with the MYO1F pleckstrin homology (PH) domain. Immunofluorescence revealed colocalisation of MYO1F and the CASS group of proteins at actin-rich podosomes and phagocytic cups in macrophages and microglia. Functional assays demonstrated that MYO1F recruitment to the phagocytic cup requires motor activity and intact PH and SH3 domains. We provide the first MYO1F interactome identifying adaptor proteins for MYO1F in podosomes and during phagocytosis, offering new insights into its function in disease-associated microglia during neurodegeneration.
