background:
IKI3 family is the Members of this family are components of the elongator multi-subunit component of a novel RNA polymerase II holoenzyme for transcriptional elongation.
Function:
Acts as subunit of the RNA polymerase II elongator complex, which is a histone acetyltransferase component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. Elongator may play a role in chromatin remodeling and is involved in acetylation of histones H3 and probably H4 (By similarity). Promotes organs development by modulating cell division rate. Required for auxin distribution or signaling. Prevents abscisic acid (ABA) signaling leading to stomatal closure and seedling growth inhibition. Involved in oxidative stress signaling. Prevents anthocyanins accumulation.
Subunit:
Component of the RNA polymerase II elongator complex (Elongator) made of at least six subunits, ELP1/ELO2, ELP2, ELP3/ELO3, ELP4/ELO1, ELP5, and ELP6.
Subcellular Location:
Cytoplasm (By similarity). Nucleus (By similarity).
Tissue Specificity:
Expressed in meristematic tissues of in roots, stems, leaves, seedlings, cotyledons, guard cells, floral buds, flowers, siliques, and shoot apices.
Similarity:
Belongs to the ELP1/IKA1 family.
Contains 7 WD repeats.

拟南芥是一种十字花科植物，广泛用于植物遗传学、发育生物学和分子生物学的研究，已成为一种典型的模式植物。
由于这种植物的全部基因组测序已经完成，因此可以预测，拟南芥在植物学所有领域的研究中将发挥更大的作用。虽然这种植物在许多方面"简单"，但它的大多数基因与其他"复杂"的植物基因具有很高的同源性。
该植物具有以下特点：
（1）形态个体小，高度只有3Ocm左右；
（2）生长周期快，从播种到收获种子一般只需6周左右；
（3）种子多，每株每代可产生数千粒种子；
（4）形态特征简单；
（5）基因组小，只有5对染色体。
