Gene

TIP1-1

Organism
Zea mays (Maize)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Water channel required to facilitate the transport of water across cell membrane. May support the rapid influx of water into vacuoles during cell expansion, permit osmotic equilibration between the cytosol and the vacuolar content and rapid transcellular water flow through living cells. Its function is impaired by Hg2+.1 Publication

Expressioni

Tissue specificityi

Expressed in roots, shoots, leaves, tassels, ears and embryos. Expressed in meristems and zones of cell enlargement: tips of primary and lateral roots, leaf primordia, and male and female inflorescence meristems. Highly expressed in the root epidermis and endodermis, parenchyma cells surrounding mature xylem vessels in the root and the stem, phloem companion cells and a ring of cells around the phloem strand in the stem and the leaf sheath, and the basal endosperm transfer cells in developing kernels.2 Publications

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.
