High impact information on tea1

 

Biological context of tea1

  • In addition, we show that S. pombe cells carrying the orb2-34 allele of shk1 exhibit a pattern of monopolar growth similar to that observed in tea1 Delta cells, suggesting that Shk1 and Tea1 may regulate one or more common processes involved in the regulation of polarized cell growth [3].
  • Consistent with a role for Tea1 as a potential downstream effector of Shk1, we show that a tea1 null mutation rescues the Shk1 hyperactivity-induced lethal phenotype caused by loss of function of the essential Shk1 inhibitor, Skb15 [3].
  • Like ras1 Delta and scd1 Delta, efc25 Delta is synthetically lethal with a deletion in tea1, a critical element for cell polarity control [4].
  • In the fission yeast Schizosaccharomyces pombe, interphase microtubules regulate cell polarity through proteins such as tea1p, a kelch repeat protein, and for3p, a formin that nucleates actin cable assembly at cell tips [5].
 

Associations of tea1 with chemical compounds

  • The localization of three different proteins normally found at cell ends-cortical F-actin, tea1, and an ral3 (scd2)-green fluorescent protein (GFP) fusion-is disrupted by TBZ treatment [6].
 

Other interactions of tea1

  • We found that tea1p is primarily transported on plus ends of microtubules from the vicinity of the nucleus to the cell ends, and that its movement near the nucleus is independent of the kinesin tea2p [7].
  • On the tips of microtubules, tea1p prevents the curling of microtubules around the cell ends, whereas it is required for maintaining linear cell growth and for retention of polarity factors such as the Dyrk kinase pom1p, the CLIP170-like tip1p, and tea2p at the cell ends [7].
 

Analytical, diagnostic and therapeutic context of tea1

  • Using immunofluorescence and live imaging microscopy, we have investigated the roles of the cell end marker tea1p in generating linear polarized growth [7].
