Form Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Protein FAQs
Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time 18-23 business days
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Seems to be a coreceptor in inhibin signaling, but seems not to be a high-affinity inhibin receptor. Antagonizes activin A signaling in the presence or absence of inhibin B. Necessary to mediate a specific antagonistic effect of inhibin B on activin-stimulated transcription.
Gene References into Functions
  1. A novel mutation (c.2713C>T, p.Q905X) of the IGSF1 gene was identified that causes congenital central hypothyroidism in a Japanese family. The findings further expand the clinical heterogeneity of this entity. PMID: 27762734
  2. We identified a novel insertion mutation in the IGSF1 gene and further delineated the phenotype of the IGSF1-deficiency syndrome. Our findings indicate a possible association between an IGSF1 mutation and neurological phenotypes. PMID: 27310681
  3. Individuals with identical IGSF1 deletions can exhibit variable pituitary hormone deficiencies, of which overt TSH deficiency is the most consistent feature PMID: 27146357
  4. IGSF1 Deficiency is associated with X-linked IGSF1 deficiency syndrome. PMID: 26840047
  5. Adult male patients with IGSF1 deficiency exhibit mild deficits in attentional control on formal testing. PMID: 26387489
  6. This case suggests that more attention should be paid to intrauterine growth and birth history when patients are suspected of having an IGSF1 mutation PMID: 26302767
  7. There is insufficient evidence to conclude that the three observed VUCSs in IGSF1 are associated with CDGP, making it unlikely that IGSF1 mutations are a prevalent cause of CDGP. PMID: 25354429
  8. Immunohistochemistry showed increased IGSF1 staining in the GH-producing tumor from the patient with the IGSF1 p.N604T variant compared with a GH-producing adenoma from a patient negative for any IGSF1 variants and with normal control pituitary tissue. PMID: 25527509
  9. Data suggest male subjects with IGSF1 deficiency syndrome exhibit X-linked congenital/central hypothyroidism, delayed puberty, macro-orchidism, hypoprolactinemia, metabolic syndrome, and transient partial growth hormone deficiency. [CASE REPORTS] PMID: 24108313
  10. Our findings provide additional genetic evidence that loss-of-function mutations in IGSF1 cause an X-linked form of C-CH and variable prolactin deficiency. PMID: 23966245
  11. Using exome and candidate gene sequencing, 8 distinct mutations and 2 deletions in IGSF1 were identified in males from 11 unrelated families with central hypothyroidism, testicular enlargement and variably low prolactin concentrations. PMID: 23143598
  12. IgSF1 is processed through sequential proteolysis by signal peptidase and signal peptide peptidase PMID: 18981173
