General description

Small ubiquitin-related modifier 1 (SUMO-1) is a highly conserved small ubiquitin-related modifier, also known as sentrin. SUMO-1 gene is mapped to human chromosome 2q33.1.

Specificity

Anti-SUMO-1 (C-terminal) recognizes unconjugated SUMO-1 (14 kDa), SUMO-1-fusion protein, as well as proteins covalently conjugated to SUMO-1, eg. RanGAP1, 90kDa

Immunogen

synthetic peptide corresponding to amino acids 86-97 located at the C-terminus of human SUMO-1, conjugated to KLH. This sequence is identical in many species including rat, mouse, bovine, chicken, and Xenopus, and highly conserved (single amino acid substitution) in C. elegans SMT3. The sequence has only 66% homology to human SUMO-2 and SUMO-3.

Application

Anti-SUMO-1 (C-terminal) antibody produced in rabbit has been used in immunoblotting.

Biochem/physiol Actions

Small ubiquitin-related modifier 1 (SUMO-1) is covalently conjugated to the lysine side in proteins through its C-terminal glycine residue by an isopeptide bond. Their conjugation with cellular proteins has been correlated wide variety of biological processes including inflammation, oncogenesis nuclear transport, cell cycle control and viral infection response. SUMO-1 serves as a substrate for Ran GTPase-activating protein (RanGAP1). Unmodified RanGAP1 is present in the cytoplasm, suggesting that modification by SUMO-1 may target RanGAP1 to the nuclear pore complex (NPC). Haploinsufficiency in the SUMO-1 gene is implicated in the Cleft Lip and Palate.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

The sumoylation (SUMO) pathway is involved in a variety of processes during C. elegans development, such as gonadal and vulval fate specification, cell cycle progression and maintenance of chromosome structure. The ubiquitous expression and pleiotropic effects have made it difficult

GTF2IRD1 is one of the genes implicated in Williams-Beuren syndrome, a disease caused by haploinsufficiency of certain dosage-sensitive genes within a hemizygous microdeletion of chromosome 7. GTF2IRD1 is a prime candidate for some of the major features of the disease

In vertebrates, establishment of the hematopoietic stem/progenitor cell (HSPC) pool involves mobilization of these cells in successive developmental hematopoietic niches. In zebrafish, HSPCs originate from the ventral wall of the dorsal aorta (VDA), the equivalent of the mammalian aorta-gonad-mesonephros (AGM).
