Summaries for SBF2 Gene

Entrez Gene Summary for SBF2 Gene

  • This gene encodes a pseudophosphatase and member of the myotubularin-related protein family. This gene maps within the CMT4B2 candidate region of chromosome 11p15 and mutations in this gene have been associated with Charcot-Marie-Tooth Disease, type 4B2. [provided by RefSeq, Jul 2008]

GeneCards Summary for SBF2 Gene

SBF2 (SET Binding Factor 2) is a Protein Coding gene. Diseases associated with SBF2 include Charcot-Marie-Tooth Disease, Type 4B2 and Neuropathy, Congenital Hypomyelinating. Among its related pathways are RAB GEFs exchange GTP for GDP on RABs and Vesicle-mediated transport. GO annotations related to this gene include protein homodimerization activity and phosphatidylinositol binding. An important paralog of this gene is SBF1.

UniProtKB/Swiss-Prot for SBF2 Gene

  • Guanine nucleotide exchange factor (GEF) which may activate RAB28. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form.

  • Charcot-Marie-Tooth disease 4B2 (CMT4B2) [MIM:604563]: A recessive demyelinating form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Demyelinating neuropathies are characterized by severely reduced nerve conduction velocities (less than 38 m/sec), segmental demyelination and remyelination with onion bulb formations on nerve biopsy, slowly progressive distal muscle atrophy and weakness, absent deep tendon reflexes, and hollow feet. By convention autosomal recessive forms of demyelinating Charcot-Marie-Tooth disease are designated CMT4. {ECO:0000269 PubMed:12554688, ECO:0000269 PubMed:12687498, ECO:0000269 PubMed:15304601, ECO:0000269 PubMed:15477569}. Note=The disease is caused by mutations affecting the gene represented in this entry.
