CC   -!- FUNCTION: Actin-myosin network stability during cellularization. Might
CC       be involved in increasing actin-actin interactions or membrane-to-
CC       cytoskeleton attachments. nullo together with Sry-a and bnk may provide
CC       auxiliary functions, by acting both to stabilize a large and dynamic
CC       microfilament structure and regulate its functions.
CC       {ECO:0000269|PubMed:1378418}.
CC   -!- TISSUE SPECIFICITY: Blastoderm. Throughout the entire cortex of the
CC       embryo although the distribution is not uniform.
CC       {ECO:0000269|PubMed:1378418}.
CC   -!- DEVELOPMENTAL STAGE: Appears first at nuclear cell cycle 11 and
CC       disappears rapidly as cellularization begins. During cycle 14, nullo
CC       protein levels are coupled to the nucleocytoplasmic ratio.
CC       {ECO:0000269|PubMed:1378418}.
