Plays a crucial role in the formation of lipid droplets (LDs) which are storage organelles at the center of lipid and energy homeostasis (PubMed:19278620, PubMed:21533227, PubMed:31708432, PubMed:30293840).

In association with LDAF1, defines the sites of LD formation in the ER (PubMed:31708432).

Also required for growth and maturation of small nascent LDs into larger mature LDs (PubMed:27564575).

Mediates the formation and/or stabilization of endoplasmic reticulum-lipid droplets (ER-LD) contacts, facilitating protein and lipid delivery from the ER into growing LDs (PubMed:31178403, PubMed:27879284).

Regulates the maturation of ZFYVE1-positive nascent LDs and the function of the RAB18-ZFYVE1 complex in mediating the formation of ER-LD contacts (PubMed:30970241).

Binds anionic phospholipids including phosphatidic acid (PubMed:30293840).

Plays an important role in the differentiation and development of adipocytes (By similarity).

Spastic paraplegia 17, autosomal dominant (SPG17)4 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPG17 is characterized by prominent amyotrophy of the hand muscles, the presence of mild to severe pyramidal tract signs and spastic paraplegia. SPG17 is a motor neuron disease overlapping with distal spinal muscular atrophy type 5.

Neuronopathy, distal hereditary motor, 5C (HMN5C)2 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA form of distal hereditary motor neuronopathy, a heterogeneous group of neuromuscular diseases caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. HMN5C is characterized by distal muscular atrophy primarily affecting the upper limbs. Lower limb involvement may occur at the same time or later. Clinical features are highly variable even within families, and include poor fine hand motor skills, difficulty walking, foot deformities, spasticity and hyperreflexia. Some HMN5C patients show axonal peripheral neuropathy and distal sensory impairment. HMN5C inheritance is autosomal dominant with incomplete penetrance.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i9FB1B37E72493DB9
