General annotation (Comments)
| Function | Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(s) protein is involved in hormonal regulation of adenylate cyclase: it activates the cyclase in response to beta-adrenergic stimuli. XLas isoforms interact with the same set of receptors as Gnas isoforms By similarity. UniProtKB Q63803 UniProtKB Q6R0H7 |
| Subunit structure | G proteins are composed of 3 units; alpha, beta and gamma. The alpha chain contains the guanine nucleotide binding site. Interacts through its N-terminal region with ALEX which is produced from the same locus in a different open reading frame. This interaction may inhibit its adenylyl cyclase-stimulating activity By similarity. UniProtKB Q63803 UniProtKB Q6R0H7 |
| Subcellular location | Cell membrane; Peripheral membrane protein By similarity UniProtKB Q63803. |
| Involvement in disease | GNAS hyperfunction (GNASHYP) [MIM:139320]: This condition is characterized by increased trauma-related bleeding tendency, prolonged bleeding time, brachydactyly and mental retardation. Both the XLas isoforms and the ALEX protein are mutated which strongly reduces the interaction between them and this may allow unimpeded activation of the XLas isoforms. ACTH-independent macronodular adrenal hyperplasia (AIMAH) [MIM:219080]: A rare adrenal defect characterized by multiple, bilateral, non-pigmented, benign, adrenocortical nodules. It results in excessive production of cortisol leading to ACTH-independent Cushing syndrome. Clinical manifestations of Cushing syndrome include facial and trunkal obesity, abdominal striae, muscular weakness, osteoporosis, arterial hypertension, diabetes. Pseudohypoparathyroidism 1B (PHP1B) [MIM:603233]: A disorder characterized by end-organ resistance to parathyroid hormone, hypocalcemia and hyperphosphatemia. Patients affected with PHP1B lack developmental defects characteristic of Albright hereditary osteodystrophy, and typically show no other endocrine abnormalities besides resistance to PTH. Pseudohypoparathyroidism 1C (PHP1C) [MIM:612462]: A disorder characterized by end-organ resistance to parathyroid hormone, hypocalcemia and hyperphosphatemia. It is commonly associated with Albright hereditary osteodystrophy whose features are short stature, obesity, round facies, short metacarpals and ectopic calcification. |
| Miscellaneous | This protein is produced by a bicistronic gene which also produces the ALEX protein from an overlapping reading frame By similarity. UniProtKB Q63803 The GNAS locus is imprinted in a complex manner, giving rise to distinct paternally, maternally and biallelically expressed proteins. The XLas isoforms are paternally derived, the Gnas isoforms are biallelically derived and the Nesp55 isoforms are maternally derived. |
| Sequence similarities | Belongs to the G-alpha family. G(s) subfamily. |
| Sequence caution | The sequence CAB83215.1 differs from that shown. Reason: Frameshift at position 40. The sequence CAM28315.1 differs from that shown. Reason: Erroneous gene model prediction. |
Ontologies
Alternative products
| This entry describes 7 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform XLas-1 Ref.1 (identifier: Q5JWF2-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: Gene prediction confirmed by EST data. | ||||||
| Isoform XLas-2 Ref.1 (identifier: Q5JWF2-2) The sequence of this isoform differs from the canonical sequence as follows: 714-729: EGGEEDPQAARSNSDG → DS | ||||||
| Note: Gene prediction confirmed by EST data. | ||||||
| Isoform XLas-3 Ref.4 (identifier: Q5JWF2-3) The sequence of this isoform differs from the canonical sequence as follows: 691-752: AGESGKSTIV...KEAIETIVAA → RKVVPSDTEG...VLENLVKAPL 753-1037: Missing. | ||||||
| Isoform Gnas-1 (identifier: P63092-1) Also known as: Alpha-S2; GNASl; Alpha-S-long; The sequence of this isoform can be found in the external entry P63092. Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly. | ||||||
| Isoform 3 (identifier: P63092-3) The sequence of this isoform can be found in the external entry P63092. Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform Gnas-2 (identifier: P63092-2) Also known as: Alpha-S1; GNASs; Alpha-S-short; The sequence of this isoform can be found in the external entry P63092. Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly. | ||||||
| Isoform Nesp55 (identifier: O95467-1) The sequence of this isoform can be found in the external entry O95467. Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly. | ||||||
| Note: Shares no sequence similarity with other isoforms due to a novel first exon containing the entire reading frame spliced to shared exon 2 so that exons 2-13 make up the 3'-UTR. |
