Costal2 Functions as a Kinesin-like Protein in the Hedgehog Signal Transduction Pathway
The Hedgehog (Hh) signaling pathway initiates an evolutionarily conserved developmental program required for the proper patterning of many tissues [1]. Although Costal2 (Cos2) is a requisite component of the Hh pathway, its mechanistic role is not well understood. Because of its primary sequence, Cos2 was initially predicted to function as a kinesin-like protein [2]. However, evidence showing t...
متن کاملHedgehog Elicits Signal Transduction by Means of a Large Complex Containing the Kinesin-Related Protein Costal2
The hedgehog gene of Drosophila melanogaster encodes a secreted protein (HH) that plays a vital role in cell fate and patterning. Here we describe a protein complex that mediates signal transduction from HH. The complex includes the products of at least three genes: fused (a protein-serine/threonine kinase), cubitus interruptus (a transcription factor), and costal2 (a kinesin-like protein). The...
متن کاملA homologue of the Drosophila kinesin-like protein Costal2 regulates Hedgehog signal transduction in the vertebrate embryo.
Orthologues of nearly all of the core components of the Hedgehog signalling pathway, defined originally through genetic analysis in Drosophila, have now been discovered in vertebrates and shown to have highly conserved functions. The one striking exception to this rule is the kinesin-like protein Costal2, which plays a central role in controlling the activity of the zinc-finger-containing trans...
متن کاملCostal2, a Novel Kinesin-Related Protein in the Hedgehog Signaling Pathway
The Hedgehog (HH) signaling proteins control cell fates and patterning during animal development. In Drosophila, HH protein induces the transcription of target genes encoding secondary signals such as DPP and WG proteins by opposing a repressor system. The repressors include Costal2, protein kinase A, and the HH receptor Patched. Like HH, the kinase Fused and the transcription factor Cubitus in...
متن کاملFrontiers in hedgehog signal transduction.
The hedgehog (Hh) pathway is a paracrine cell–cell communicaion system discovered in Drosophila over thirty years ago and then tudied for its central role in development in both vertebrates and nvertebrates. Hh was later implicated in other processes, includng adult stem cell maintenance, cell migration, axon guidance and ancer, in a wide range of organisms. Its identification as an oncoenic dr...
