General annotation (Comments)

Function

Major glycoprotein component of a variety of mucus gels. Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. May be involved in ligand binding and intracellular signaling. Ref.8

Subcellular location

Isoform 1: Membrane; Single-pass membrane protein.

Isoform 2: Secreted.

Isoform 3: Secreted.

Isoform 4: Secreted.

Isoform 5: Secreted.

Tissue specificity

Broad specificity; small intestine, colon, colonic tumors, heart, liver, thymus, prostate, pancreas and gall bladder. Ref.7

Post-translational modification

Highly O-glycosylated and probably also N-glycosylated.

Sequence similarities

Contains 1 EGF-like domain.

Contains 1 SEA domain.

Alternative products

This entry describes 5 isoforms produced by alternative splicing. [Align] [Select]

Note: Additional isoforms seem to exist.
Isoform 1 (identifier: Q02505-1)

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.
Isoform 2 (identifier: Q02505-2)

The sequence of this isoform differs from the canonical sequence as follows:
     2237-2284: VVETEVGMEV...MQKIFADMQG → AEDFCRHAGL...ALQPPAGERV
     2285-2541: Missing.
Isoform 3 (identifier: Q02505-3)

The sequence of this isoform differs from the canonical sequence as follows:
     2275-2298: MQKIFADMQGFTFKGVEILSLRNG → EWQHRGGLPGPAGDALQPPAGERV
     2299-2541: Missing.
Isoform 4 (identifier: Q02505-4)

The sequence of this isoform differs from the canonical sequence as follows:
     2296-2299: RNGS → SPVF
     2300-2541: Missing.
Isoform 5 (identifier: Q02505-5)

The sequence of this isoform differs from the canonical sequence as follows:
     2422-2479: Missing.
