Cellular asymmetry is critical for the development of multicellular organisms. Here we show that homologues of proteins necessary for asymmetric cell division in Caenorhabditis elegans associate with each other in mammalian cells and tissues. mPAR-3 and mPAR-6 exhibit similar expression patterns and subcellular distributions in the CNS and associate through(More)
The evolutionarily conserved proteins Par-6, atypical protein kinase C (aPKC), Cdc42 and Par-3 associate to regulate cell polarity and asymmetric cell division, but the downstream targets of this complex are largely unknown. Here we identify direct physiological interactions between mammalian aPKC, murine Par-6C (mPar-6C) and Mlgl, the mammalian orthologue(More)
The neurotrophin receptor TrkA plays critical roles in the nervous system by recruiting signaling molecules that activate pathways required for the growth and survival of neurons. Here, we report APPL1 as a TrkA-associated protein. APPL1 and TrkA co-immunoprecipitated in sympathetic neurons. We have identified two routes through which this association can(More)
Mutations in p73 are rare in cancer. Emerging evidence suggests that the relative expression of various p73 isoforms may contribute to tumorigenesis. Alternative promoters and N-terminal splicing result in the transcription and processing of either full-length (TA) or N-terminally truncated (deltaN) p73 isoforms. TAp73 possesses pro-apoptotic functions,(More)
The mechanisms that regulate symmetric, proliferative divisions versus asymmetric, neurogenic divisions of mammalian neural precursors are still not well understood. We found that Lfc (Arhgef2), a Rho-specific guanine nucleotide exchange factor that interacts with spindle microtubules, and its negative regulator Tctex-1 (Dynlt1) determine the genesis of(More)
The p75 neurotrophin receptor (p75NTR) is required for the activity of growth cone collapsing factors such as Nogo, MAG, OMgP, and ephrin A. Specifically, p75NTR associates with the Nogo receptor and GPI-linked ephrin A, and unliganded p75NTR mediates the biological effects of those proteins. Here we assess the requirement for p75NTR for the growth cone(More)
