CC -!- FUNCTION: Elongator complex-associated factor that is not a structural
CC subunit but rather transiently contacts the complex (PubMed:25518926).
CC Regulates both meristem activity and organ growth; acts as a positive
CC regulator of adaxial leaf patterning by modulating both cell division
CC and differentiation (PubMed:12615938, PubMed:8392411, PubMed:11589569,
CC PubMed:15894610, PubMed:25518926). Required for an early step in
CC synthesis of 5-carbamoylmethyl (ncm5) groups present on uridines
CC (ncm5U) at the wobble position in tRNA (PubMed:20836892).
CC {ECO:0000250|UniProtKB:P34253, ECO:0000269|PubMed:11589569,
CC ECO:0000269|PubMed:12615938, ECO:0000269|PubMed:15894610,
CC ECO:0000269|PubMed:20836892, ECO:0000269|PubMed:25518926,
CC ECO:0000269|PubMed:8392411}.
CC -!- SUBUNIT: Interacts with the elongator complex (By similarity). Binds to
CC calmodulin in a calcium-dependent manner (PubMed:12615938).
CC {ECO:0000250|UniProtKB:P34253, ECO:0000269|PubMed:12615938}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P34253}. Nucleus
CC {ECO:0000250|UniProtKB:P34253}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, hypocotyls, cotyledons, shoot
CC apices, stems, inflorescence apices, leaves and flowers.
CC {ECO:0000269|PubMed:12615938}.
CC -!- DEVELOPMENTAL STAGE: Detected in globular-, heart-, and torpedo-stage
CC embryos, in the outer integuments of ovules and in the funiculi. Also
CC expressed in the peripheral zone of the shoot apical meristem (SAM)
CC corresponding to the central zone. In elongating tissues, restricted at
CC the periphery of the vascular bundle. In shoot and inflorescence
CC apices, mostly present in the L2 layer, and, at lower levels, in the L1
CC layer, but absent of the L3 layer. In young leaf primordia, localized
CC in the basal part of the dorsal side. In older leaf primordia, detected
CC in vascular bundles and in the mesophyll between the vascular bundles.
CC In expanding leaves, confined to stomatal guard cells, and individual
CC palisade and spongy mesophyll parenchyma cells. In general, present
CC around the vascular bundles. Expressed in young flower organs but not
CC in mature sepals and petals. Gradient accumulation in the stamens and
CC carpels, with the highest activity at the tip of the organs. Present in
CC the meristematic and elongation zones of the primary root and in the
CC vascular bundle of the differentiation zone.
CC {ECO:0000269|PubMed:12615938}.
CC -!- DISRUPTION PHENOTYPE: Defective organ formation due to disorganized
CC shoot, inflorescence, flower, and root meristems leading to stunted
CC roots, few root hairs, lanceolate leaves, and a highly enlarged,
CC disorganized shoot apex that does not produce an inflorescence
CC (PubMed:12615938, PubMed:8392411, PubMed:10353913, PubMed:11589569,
CC PubMed:15894610, PubMed:25518926). Altered cell division and cell
CC differentiation in leaves (PubMed:25518926). No detectable 5-
CC carbamoylmethyluridine (ncm5U) modified nucleosides (PubMed:20836892).
CC {ECO:0000269|PubMed:10353913, ECO:0000269|PubMed:11589569,
CC ECO:0000269|PubMed:12615938, ECO:0000269|PubMed:15894610,
CC ECO:0000269|PubMed:20836892, ECO:0000269|PubMed:25518926,
CC ECO:0000269|PubMed:8392411}.
CC -!- SIMILARITY: Belongs to the KTI12 family. {ECO:0000305}.
