General annotation (Comments)

Function

Stimulates lipid degradation in adipocytes and causes the extensive fat losses associated with some advanced cancers. May bind polyunsaturated fatty acids.

Subunit structure

Interacts with PIP.

Subcellular location

Secreted.

Tissue specificity

Blood plasma, seminal plasma, urine, saliva, sweat, epithelial cells of various human glands, liver.

Post-translational modification

N-glycosylated. N-glycan at Asn-128: Hex5HexNAc4. Ref.19 Ref.20 Ref.21 Ref.22

Sequence similarities

Belongs to the MHC class I family.

Contains 1 Ig-like C1-type (immunoglobulin-like) domain.

Caution

It is uncertain whether Met-1 or Met-4 is the initiator.

Sequence caution

The sequence AAA61311.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.

The sequence BAA03123.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.

The sequence BAA14417.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.

The sequence CAA42438.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
