Protein Function and Prediction |
Ift74 (alternatively, capillary morphogenesis gene (CMG)-1) is required for the expression of cyclin-D2, E-cadherin, integrin-α1, α2, α10, and α11 in a mouse premeiotic spermatocyte-derived cell line (GC-2) (1;2). CMG-1 serves as a transcriptional regulator of proliferation and adhesion-associated genes in early stage male germ-line cells in the testis (1).
|
Expression/Localization |
RT-PCR detected highest expression in adult and fetal kidney and lower expression in adult heart, placenta, lung, liver, and pancreas, and in fetal heart, lung, and liver. Little to no expression was detected in adult brain and skeletal muscle or in fetal brain, thymus, and spleen (3). CMG-1 is abundantly expressed in immature stages of male germ-line cells of the adult mouse testis (1;2)
|
Background |
Mutations within IFT74 have been found in patients with Amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia [OMIM: #105550; (4) ]. ALS patients have progressive motor neuron degeneration resulting in paralysis and death (~3-5 years after symptom onset) (4).
Knockdown of Ift74 in mouse at embryonic day 9.5 resulted in enhanced proliferation and expansion of basal keteratinocyte-like cells and a loss of cilia in epidermal keratinocytes (5). |
