KANSL3

Non-catalytic component of the NSL histone acetyltransferase complex, a multiprotein complex that mediates histone H4 acetylation at 'Lys-5'- and 'Lys-8' (H4K5ac and H4K8ac) at transcription start sites and promotes transcription initiation. The NSL complex also acts as a regulator of gene expression in mitochondria. Within the NSL complex, KANSL3 is required to promote KAT8 association with mitochondrial DNA. Required for transcription of intraciliary transport genes in both ciliated and non-ciliated cells (By similarity). This is necessary for cilium assembly in ciliated cells and for organization of the microtubule cytoskeleton in non-ciliated cells (By similarity). Also required within the NSL complex to maintain nuclear architecture stability by promoting KAT8-mediated acetylation of lamin LMNA (By similarity). Plays an essential role in spindle assembly during mitosis. Acts as a microtubule minus-end binding protein which stabilizes microtubules and promotes their assembly. Indispensable during early embryonic development where it is required for proper lineage specification and maintenance during peri-implantation development and is essential for implantation (By similarity)..
