| Primary Identifier | IPR033930 | Type | Domain |
| Short Name | FAM43A/B_PTB |
| description | Proteins encoding phosphotyrosine binding (PTB) domains function as adaptors or scaffolds to organise the signaling complexes involved in wide-ranging physiological processes including neural development, immunity, tissue homeostasis and cell growth. Due to structural differences, PTB domains are divided into three groups represented by phosphotyrosine-dependent IRS-like, phosphotyrosine-dependent Shc-like, and phosphotyrosine-independent Dab-like PTBs. The last two PTBs have been named as phosphotyrosine interaction domain (PID or PI domain). PID domain has an average length of about 160 amino acids [].The function of family with sequence similarity 43, member A (FAM43A) is currently unknown. Human FAM43A is located on chromosome 3 at location 3q29. It encodes a 3182 base pair mRNA which possesses one Pleckstrin homology-like domain. The mRNA translates into LOC131583, a hydrophilic protein that is predicted to localize in the nucleus. The FAM43A gene is conserved through a broad range of vertebrates. It is highly conserved from chimpanzees to zebrafish. This entry refers to the PTB domain found in FAM43A/B. |
