SWR1-type Domino H2Av exchange complex in Drosophila melanogaster

The SWR1-type complex deposits the histone variant H2Av into nucleosomes in exchange for H2A. Its catalytic subunit is the SWR1-family ATPase Domino; in Drosophila the Domino-B isoform forms this complex, whereas Domino-A is part of the Tip60 complex. The complex shares with Tip60 the AAA+ ATPases Pontin and Reptin, YL-1, DMAP1, Gas41, Bap55 and the MRG15 module, and contains the actin-related protein Arp6.

FlyBase gene group SWR1: Swr1 complex
FlyBase release FB2026_03 groups 12 D. melanogaster genes as swr1 complex (SWR1); this module models that group.
GO:0000812
Swr1 complex
GO term grounding the module as Swr1 complex.

Grouping of accessory subunits follows the conserved SWR1/SRCAP organisation and is a modelling convenience. The Domino isoform specificity (Domino-B here, Domino-A in Tip60) cannot be represented with gene-level participants; both modules use the dom gene product. Hcf is included because FlyBase lists it in the SWR1 group. FlyBase groups realized by this module: SWR1 (FBgg0001790). Participants were generated from the FlyBase gene-group membership and mapped to UniProtKB by projects/FLYBASE_GENE_GROUPS/generate_modules.py from module_specs/dmel_swr1_domino_complex.yaml. None of the member genes has a gene review in this repository yet.

Function consistency and core coverage

0 gene-function check(s) reflected in core functions · 0 conflict(s) · 1 evidence or coverage gap(s) (1 comparison(s))

Retained noncore functions are reported separately; they do not require promotion to core functions. Support from representative genes does not establish conservation across the whole family. Missing reviews or identifiers leave a claim unverified.
