Predicted to enable several functions, including G-protein alpha-subunit binding activity; dynein complex binding activity; and protein C-terminus binding activity. Predicted to be involved in several processes, including Ran protein signal transduction; maintenance of centrosome location; and regulation of spindle organization. Predicted to act upstream of or within establishment of mitotic spindle orientation and lung epithelial cell differentiation. Predicted to be located in several cellular components, including apical part of cell; centrosome; and lateral cell cortex. Predicted to be part of protein-containing complex. Predicted to colocalize with cell cortex and mitotic spindle pole. Human ortholog(s) of this gene implicated in sensorineural hearing loss. Orthologous to human GPSM2 (G protein signaling modulator 2). [provided by Alliance of Genome Resources, Apr 2022]
