Small ubiquitin-related modifier 1 is a protein that in humans is encoded by the SUMO1 gene.
This gene encodes a protein that is a member of the SUMO (small ubiquitin-like modifier) protein family. It functions in a manner similar to ubiquitin in that it is bound to target proteins as part of a post-translational modification system. However, unlike ubiquitin, which targets proteins for degradation, this protein is involved in a variety of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability. It is not active until the last four amino acids of the carboxy-terminus have been cleaved off. Several pseudogenes have been reported for this gene. Alternate transcriptional splice variants encoding different isoforms have been characterized.
Most cleft genes have a sumoylation component . Analysis of chromosomal anomalies in patients has led to the identification and confirmation of SUMO1 as a cleft lip and palate locus.

Famous quotes containing the word small:
“Good marriages are built on respectful disagreement and back-and-forth cooperation. We learn to cue each other, fill in for each other, forgive each other’s fumbles, celebrate small victories. We revel in the realization that we’re working on something bigger than both of us, and that parenthood is not only incredibly challenging but also incredibly enriching.”
—Susan Lapinski (20th century)
