KIAA1143 is an uncharacterized protein in humans that is encoded by the KIAA1143 gene. it may play a role in cell growth mechanisms and regulation/creation of cytoskeletal structure. This gene is located on chromosome 3 on the minus strand
This protein has a function that is not yet objectively understood. KIAA1143 has no alias and has the longest most functional variant named as uncharacterized protein KIAA1143 isoform 1. The mature mRNA transcript is 5079 Base pairs long while the length of the KIAA1143 protein is 154 amino acids. KIAA1143 has another transcript variant called KIAA1143 variant 2, which contains an alternate 3' terminal exon, resulting in a distinct 3' coding region and 3' UTR, compared to variant 1. The encoded isoform 2 has a distinct C-terminus and is shorter than isoform 1. The KIAA1143 protein belongs to the uncharacterized protein KIAA1143-like Family, and contains DUF4604 domain of unknown function. KIAA1143 has a predicted function of cell structure/mobility by encoding heavy neurofilament subunits in neurons. Immunohistochemistry staining from Thermo Fisher Scientific shows presence of KIAA1143 in a cytokinetic bridge, which is involved in cellular cytokinesis. This indicates KIAA1143 may have a role in regulation of cellular division and/or communication as well.
