Disruption phenotypei

Embryo lethality. Embryos consisting of variably enlarged cells with cell-wall stubs. Abnormal microtubule organization. Endosperm indistinguishable from wild-type endosperm in regard to nuclear multiplication and subsequent cellularization. Cells undergoing cytokinesis divide abnormally although they display pheragmoplast microtubules and accumulate KNOLLE in the forming cell plate.1 Publication

Interactioni

Subunit structurei

Monomer. Supercomplex made of cofactors A to E. Cofactors A and D function by capturing and stabilizing tubulin in a quasi-native conformation. Cofactor E binds to the cofactor D-tubulin complex; interaction with cofactor C then causes the release of tubulin polypeptides that are committed to the native state. Interacts with TUBB9.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
