Acts in the early stages of hematopoiesis.
Ligand for the receptor-type protein-tyrosine kinase KIT. Plays an essential role in the regulation of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration and function, and in melanogenesis. KITLG/SCF binding can activate several signaling pathways. Promotes phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, and subsequent activation of the kinase AKT1. KITLG/SCF and KIT also transmit signals via GRB2 and activation of RAS, RAF1 and the MAP kinases MAPK1/ERK2 and/or MAPK3/ERK1. KITLG/SCF and KIT promote activation of STAT family members STAT1, STAT3 and STAT5. KITLG/SCF and KIT promote activation of PLCG1, leading to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. KITLG/SCF acts synergistically with other cytokines, probably interleukins.
Hyperpigmentation with or without hypopigmentation, familial progressive
FPHH
A disorder characterized by hyperpigmented patches in the skin, present in early infancy and increasing in size and number with age. Hyperpigmentation has variable intensity, and sometimes is associated with cafe-au-lait macules and larger hypopigmented ash-leaf macules.
None
The disease is caused by variants affecting the gene represented in this entry.
Deafness, congenital, unilateral or asymmetric
DCUA
An autosomal dominant form of non-syndromic, sensorineural deafness characterized by inability to hear affecting one ear. Some patients suffers from asymmetric, bilateral hearing loss.
None
The disease is caused by variants affecting the gene represented in this entry.
Waardenburg syndrome 2F
WS2F
A form of Waardenburg syndrome, an auditory-pigmentary disorder characterized by sensorineural deafness, pigmentary disturbances of the hair, skin and eyes, and absence of dystopia canthorum which is the lateral displacement of the inner canthus of each eye. WS2F is an autosomal recessive form with variable expressivity, characterized by congenital or neonatal-onset sensorineural hearing loss.
None
The disease may be caused by variants affecting the gene represented in this entry.
A soluble form (sKITLG) is produced by proteolytic processing of isoform 1 in the extracellular domain.
Found in two differentially glycosylated forms, LMW-SCF and HMW-SCF. LMW-SCF is fully N-glycosylated at Asn-145, partially N-glycosylated at Asn-90, O-glycosylated at Ser-167, Thr-168 and Thr-180, and not glycosylated at Asn-97 or Asn-118. HMW-SCF is N-glycosylated at Asn-118, Asn-90 and Asn-145, O-glycosylated at Ser-167, Thr-168 and Thr-180, and not glycosylated at Asn-97.
A soluble form exists as a cleavage product of the extracellular domain.
Belongs to the SCF family.
