Description

dar1³⁰¹⁰ contains a premature stop codon so that only a fragment of the N-terminal half of the protein can be produced, without the nuclear localization signal and zinc finger domains.

Detailed Description

Statement

Reference

dar1³⁰¹⁰/dar1³⁰¹⁰ larval dendritic arborizing neurons display loss of the multipolar layout of dendrites, with many becoming bipolar.

dar1³⁰¹⁰/dar1³⁰¹⁰ larval es neurons not do not show a significant change in morphology as compared to wild type.

(Wang et al., 2015)

In dar1³⁰¹⁰ mutants, major dendrites of class IV da neurons are either missing or shortened, consequently resulting in a reduced dendritic arbor. In contrast, the axonal growth of these neurons is normal. Dendrites of class I da neurons are also severely shortened.

dar1³²³²/dar1³⁰¹⁰ mutants, generated by crossing dar1³²³² germline clones with dar1³⁰¹⁰ mutants show the same phenotype as dar1³⁰¹⁰ zygotic mutants, that is, the dendrites are reduced but the axons are normal. Dendritic defects are visible as early as 16-17 hours after egg laying and become more pronounced in 18-19 hours after egg laying, suggesting these mutants exhibit reduced outgrowth of dendrites.

Single neurons homozygous for dar1³⁰¹⁰, generated through MARCM, exhibit severely reduced dendritic arbors, supporting the notion that dar1 functions cell-autonomously. Dendrites are dramatically reduced in all four classes of da neurons (class I-ddaD and ddaE, class II-ddaB, class III-ddaA, and class IV-ddaC). In contrast, there is no significant defect in axonal growth in these mutants.

Additional Comments

Genetic Interactions

Statement

Reference

Expression of nudE^Scer\UAS.A under the control of Scer\GAL4^unspecified partially rescues the increased number of bipolar dendritic arborizing neurons seen in dar1³⁰¹⁰/dar1³⁰¹⁰ mutant clones.

(Wang et al., 2015)

A dar1³⁰¹⁰ mutant background suppresses the increase in dendrite length found upon expression of kn^Scer\UAS.cMa in class I da neurons under the control of Scer\GAL4^21-7 and results in a severe reduction in dendrite length.

A dar1³⁰¹⁰ mutant background does not block the dendrite branching activity found upon expression of Rac1^Scer\UAS.cLa under the control of Scer\GAL4⁴⁷⁷.
