of subsynaptic reticulum and F-actin stability, contributes to coupling the plasma membrane and contractile ring in cytokinesis

Talin
essential for integrin function - crosslinks extracellular matrix-linked integrins to the cytoskeleton

tarsal-less
codes for short encoded peptides that convert Shavenbaby from a transcriptional repressor to an activator
via the truncation of its N-terminal region - polycistronic message - epidermal differentiation - spatial pattern of trichomes - legs - trachea

tau

microtubule-associated protein - delivery of synaptic proteins - vesicular axonal transport - a target for PAR-1
in dendritic pruning - Dendrite severing - regulation of photoreceptor development and progressive neuronal degeneration

torsolike
terminal system - follicle cell protein

Troponin I (FlyBase name: wings up A)
cytoskeletal protein - along with Tropomyosin regulates muscle contraction - required to maintain nuclear integrity and
apico-basal polarity during early embryogenesis - required for myofibrillogenesis and sarcomere formation in Drosophila flight muscle

β1 Tubulin
β Tubulin56D - ubiquitious component of cytoskeleton

β2 Tubulin
β Tubulin85D - sperm tubulin

β3 Tubulin
β Tubulin60D - microtubular cytoskeleton

γ Tubulin
gamma Tubulin at 23C - microtubule nucleating factor

γ-Tubulin at 37C
microtubule nucleating factor - eggs produced by mutant mothers show an arrest of nuclear divisions
during early embryogenesis and a disruption in the anterior-posterior axis - required for bicoid mRNA localization

tubulin-specific chaperone E
multidomain protein - required for development and function of neuromuscular synapses - promotes microtubule formation

twinstar
Drosophila cofilin - actin-depolymerizing and actin-severing protein - essential for neuronal axon growth

unc-104
a Kinesin-3 family member that is essential for transporting synaptic vesicle precursors

unconventional myosin class XV (common alternative names: Myo10A and Sisyphus)
cytoskeletal motor protein - regulates filopodial dynamics during dorsal closure

uncoordinated
coiled-coil protein expressed in sensory neurons and the male germline - localizes to centrioles and basal bodies - required for ciliogenesis

unkempt
C3HC4 type (RING finger) protein - works downstream of insulin receptor/mTOR pathway to regulate temporal control of neuronal differentiation

Vacuolar protein sorting 35
a subunit of the retromer complex which is essential for the retrograde transport of numerous transmembrane proteins
from endosomes to the trans-Golgi network - required apical localization of key apical/basal polarity molecules

valois
scaffolding protein - required for accumulation of high levels of Oskar protein, for posterior localization of Oskar in later stages of oogenesis
and for posterior localization of the Vasa protein during pole plasm assembly

varicose
Essential septate junction gene encoding a membrane associated guanylate kinase (MAGUK) - required for accumulation of the tracheal
size-control proteins Vermiform and Serpentine in the tracheal lumen

veli (common alternative name: Lin-7)
scaffolding protein that acts downstream of DlgS97, in conjunction with its binding partner Metro, to control neuromuscular
junction expansion and proper establishment of synaptic boutons

verthandi
constituent of the cohesin complex, functions in chromosome cohesion, spindle morphology, dynamics of a chromosome passenger protein,
and stability of the cohesin complex

Vinculin
component of adherens and focal adhesion junctions - regulates cytoskeletal anchoring at the plasma membrane - regulates cell
adhesion - mechanotransduction - triggers the formation of cytoplasmic adhesion complexes - interacts with α-Catenin - recruited
to amniosersoa apical cell membranes during dorsal closure - regulates of cardiac function during aging

viriato
nucleolar protein of unknown function - ensures a coordinated nucleolar response to dMyc-induced growth -
required for the growth and differentiation progression activities of the Dpp pathway during eye development

wech (common alternative name: dappled)
LIN-41 subclade multiple domain protein of unknown function - let-7 micro RNA regulated

wings up A (common alternative name: Troponin I)
cytoskeletal protein - along with Tropomyosin regulates muscle contraction - required to maintain nuclear integrity and
apico-basal polarity during early embryogenesis - required for myofibrillogenesis and sarcomere formation in Drosophila flight muscle

Wrinkled (common alternative name: head involution defective)
death domain protein - programmed cell death
